Ready to make your resume not just good, but great? Let’s jump in and discover how to create a professional CV that paves the way to your dream job!

🚫 Avoid These Common Pitfalls

Heavy Blocks of Text

It’s important to understand that recruiters often have limited time to review each resume. They typically skim through them to find key information quickly. This means that resumes with dense, long paragraphs are less likely to hold their attention. By contrast, resumes with clear, concise content are more effective in catching and keeping a recruiter’s interest.

Wrong Format

If a job ad specifies a format, follow it religiously. This could be due to compatibility with the Applicant Tracking System (ATS). Ignoring format specifications can lead to a resume being directly rejected or overlooked. The ATS may fail to parse critical information from the resume or incorrectly categorize it, resulting in a lower ranking among other candidates. This makes adherence to the specified format not just a matter of preference but a critical step in ensuring the resume is effectively reviewed.

Bad styling

The choice of text colors and fonts in a resume can significantly impact its professionalism. Bright, flashy colors or hard-to-read fonts can appear unprofessional and may distract from the content of the resume. It’s important to remember that a resume is a formal document and its appearance should reflect that.

Europass CV

While the Europass CV format has been widely used for years, it’s increasingly viewed as outdated in today’s dynamic job market. Employers no longer specifically require this format, opening the door for more contemporary and innovative resume styles. Consider adopting newer formats that allow for greater flexibility and personalization, ensuring that your resume effectively showcases your unique skills and experiences.

False Information

Never lie on your resume. Overstating your position or qualifications can backfire, especially if the truth surfaces later. Never lie on your resume. Being honest and transparent about your skills and experiences is the best policy. Integrity speaks volumes. Always.

Irrelevant and Really Old Employment History

Ensure that your work experience aligns with the role for which you are applying. Highlight transferable skills if you are transitioning between industries, but avoid listing irrelevant job experiences or positions held more than two decades ago. There’s no need to mention the job you had as a teenager unless you’re a very young candidate with no prior experience.

Too Much Personal Info

In most Western countries, details like your street address, gender, age, religion, marital status, or nationality are unnecessary and can inadvertently lead to unconscious bias in the recruitment process. Recruiters and hiring managers are humans and may hold subconscious prejudices that could influence their decision-making. The focus should be on skills, experiences, and qualifications relevant to the job.

Inappropriate Email Address

Using a current work email for job applications is not advisable. It can be seen as unprofessional or a breach of your current employer’s trust. Moreover, it could lead to awkward situations if your job search becomes known to your current employer.

Additionally, email addresses that are frivolous, suggestive, or unprofessional (like hotguy69@example.com) can create a negative impression. Such addresses can be seen as immature or unprofessional, potentially leading recruiters to question the applicant’s judgment and professionalism. Remember, the contact information on a resume is often the first thing recruiters notice.

Questionable Work Experience

It’s generally advisable to omit experiences where you were fired or left under contentious circumstances. Including such experiences can raise red flags for potential employers and lead to uncomfortable questions during interviews. Unless you are Sam Altman and the whole world already knows you were kicked out, so it doesn’t matter if you put that in your resume. Just focus on positive experiences and achievements.

Past Salary Info – A big NO

Including past salary details on a resume is generally considered inappropriate and irrelevant. A resume is meant to showcase your skills, experiences, and achievements, not your financial history. Mentioning past compensation doesn’t add value to your qualifications for the job.

Stating your past salaries can also inadvertently set a benchmark for future compensation. If your previous salary was lower than the market rate for the position you’re applying for, you might be unintentionally setting a lower expectation for your new salary. Similarly, if your past salary was high, it might lead potential employers to assume you’re out of their budget.

Unnecessary Info About Previous Employers and Experience

Including the full address of previous employers on a resume is generally unnecessary. It’s not typically relevant to your qualifications or the job you’re applying for. Including just the city is sufficient to provide a geographical context of your past work experience.

Also, while it’s important to provide a timeline of your work history, the exact start and end dates (day, month, and year) of each employment are not necessary. Instead, listing the duration in years and months is usually adequate and simplifies the resume. This approach still gives potential employers a clear understanding of the length of time you spent in each role.

Personal Hobbies and Interests

Given the limited space on a resume, it’s crucial to prioritize the most important information. Including hobbies and interests can sometimes take up valuable space that could be used to elaborate on your skills and experiences. Unless they’re directly relevant to the job or add a unique dimension to your profile, it’s best to leave out hobbies and interests from your resume.

Fluff and Buzzwords

Terms like “results-oriented,” “team-player,” or “hardworking” are often overused in resumes and have become clichés. These terms are so broad and subjective that they fail to convey meaningful information about the candidate’s actual skills and experiences. Using clichéd phrases can make your resume blend in with countless others, reducing its ability to stand out. Recruiters who see these terms frequently may overlook them, diminishing the impact of your resume.

Errors

Nothing undermines a professional resume more than typos and grammatical errors. Such mistakes can give the impression of carelessness and a lack of attention to detail. In a document that’s meant to showcase your best self, errors can be a major detractor.

It’s essential to thoroughly proofread your resume multiple times. This helps catch any errors that might have been missed in earlier drafts. Proofreading is not just about checking for spelling mistakes, but also for grammatical errors, punctuation, and consistency in format and style.

🟢 Do Implement These Strategies

Clarity and Brevity Speak Volumes

The most effective resumes are clear, concise, and to the point. You can utilize bullet points to break down information into easily digestible pieces. Each bullet point can highlight a specific skill, achievement, or experience, making it easier for the recruiter to identify the candidate’s qualifications. This format also encourages the writer to be more concise and to the point.

Also, make sure you use short, impactful sentences to help you make a stronger impression. These sentences should be action-oriented, emphasizing achievements and skills. For example, instead of saying “I was involved in project management,” a more impactful sentence would be “Led a team of 10 in a successful project deployment.”

Make Your Resume a Perfect Fit

Generic resumes rarely make the cut. On the other hand, customizing the resume for each application, including formatting and content, shows that you have put thought and effort into your application and demonstrates your understanding of the role and its requirements. This customization can make a significant difference, especially when the job market is highly competitive.

Numbers Tell a Story

Quantify your achievements where possible. Numbers provide a concrete measure of your capabilities and make your accomplishments more tangible and credible. They offer a clear and objective way to demonstrate the extent of your contributions and successes. This can be particularly persuasive to potential employers, as it provides them with a measurable indicator of your capabilities. The use of infographics can also be a nice addition, wherever appropriate.

Keep it Clean and Professional

Your resume’s layout should be clean and organized, making it easy for recruiters to scan and appreciate your qualifications. Small details like font choice and spacing can make a big difference. In the end, well-executed minimalism is always classy and gets the right attention. Opting for standard, easy-on-the-eyes fonts (such as Arial, Times New Roman, or Calibri) and colors enhances readability and presents a clean, professional look. Standard fonts are also more likely to be compatible with ATS systems, ensuring that the text is parsed correctly.

Color psychology can also be subtly employed to influence how recruiters perceive your resume. Different colors can evoke different emotions and associations. For example, blue is often associated with trust and reliability, which might be beneficial for positions in finance or law. However, it’s crucial to understand the culture of the industry you’re applying to, as color perceptions can vary.

A Summary Can Make a Big Difference

A resume summary is a brief section at the top of a resume that highlights your key skills, experiences, and achievements. It provides a quick overview of your professional background and what you bring to the table. It’s especially beneficial for experienced professionals to help them concisely present a long and varied career. It allows them to showcase their most significant accomplishments and skills upfront, ensuring that these highlights don’t get lost in a lengthy work history.

It’s also a great option for those who have undergone a career change. A summary is particularly useful in outlining transferable skills. It can help draw connections between past experiences and the requirements of the new field or position. For example, a former teacher moving into corporate training can highlight skills in presentation, curriculum development, and educational needs assessment.

If you have no experience, a summary could help you as well by focusing on educational achievements, relevant skills, and personal attributes. It’s an opportunity to showcase enthusiasm, potential, and how one’s skills align with the job requirements. Tailoring this summary to each specific job application can help you highlight your suitability and readiness for the role.

Remember: a summary should be brief yet impactful. Typically, a few sentences are enough to convey the essential aspects of your background. The goal is to be succinct but powerful in your language.

The Power of Keywords

In the age of digital recruitment, including relevant keywords is vital. Use terms and phrases from the job description. This not only demonstrates that you’re a good fit but also helps your resume get past applicant tracking systems (ATS) that use AI. These systems scan resumes for specific keywords related to the job opening. Resumes that contain more of these keywords are more likely to be passed on for further review by a recruiter or hiring manager. However, be cautious of overloading your resume with keywords that can make your resume seem unnatural and even be flagged by more sophisticated ATS as potentially manipulative.

A Picture is Worth a Thousand Words

A professional headshot adds a personal touch to your resume. It gives a face to the name and can help create a connection with the recruiter or hiring manager. The headshot should represent you in a professional manner. This means choosing a photo where you are dressed in professional or business-appropriate attire, similar to what you would wear to a job interview for the role you are applying for.

The photo should be of high quality, with good lighting and focus. Ensure that your face is clearly visible, and the expression is friendly and approachable. The background of the photo should be neutral and non-distracting. A simple, solid color background or a professional setting is preferable. Avoid busy backgrounds that can take the focus away from you.

Cultural and Industry Considerations: It’s important to consider the cultural norms and industry standards when deciding to include a headshot. In some cultures and industries, adding a photo is common, while in others, it can be seen as unprofessional or unnecessary.

Continuous Updates: Keep It Fresh

Treating your resume as a living document means recognizing that it should evolve over time. As you gain new experiences, skills, and achievements, your resume should be updated to reflect these changes. This approach keeps your professional profile current and relevant. If you have an online resume or a LinkedIn profile, regular updates are equally important. These platforms are often the first place potential employers or recruiters will look to learn more about you.

In a Nutshell

Creating an effective resume is an art that requires attention to detail, a deep understanding of the job market, and a personal touch in branding. By following these tips, you’re not just creating a document; you’re crafting the first impression a potential employer will have of you. Let your resume reflect your professionalism, skills, and unique personality. Knowing how to create a professional CV, you’re well on your way to securing that coveted interview and stepping into your dream job. Remember, a great resume is the first step to career success.

Good luck with your job search!

How to Explain Blockchain in an Interview

When describing blockchain in an interview, make sure you offer a clear and concise explanation. Here’s a simple definition of a blockchain:

Think of blockchain as a unique digital ledger or record-keeping system that tracks transactions. Picture a giant notebook that anyone can write in, but once something is written, it can’t be changed or deleted.

Instead of being stored in a single place, the information is spread across many computers around the world, known as nodes. These computers collaborate to ensure the information is accurate and secure. Think of it as multiple people double-checking and verifying information for accuracy.

Each transaction forms a group with other transactions, creating a “block.” These blocks then interconnect and form a “chain,” hence the name blockchain.

Since the data is distributed across numerous computers and can’t be easily altered, the blockchain is extremely secure. Altering records or gaming the system is nearly impossible, as it would require changing the data on all the computers simultaneously.

While mainly associated with cryptocurrencies, blockchain technology has uses in various sectors such as monitoring supply chains, confirming digital identities, and designing decentralized applications (DApps) that run on blockchains.

In a nutshell, a blockchain is a special digital ledger that securely and transparently records transactions by storing the data on numerous computers. It forms a chain of information that’s difficult to tamper with, providing trust and security in a decentralized manner.

What is the difference between crypto and web3?

Cryptocurrency (Crypto)

Cryptocurrency, or “crypto”, refers to digital or virtual currencies that leverage cryptography for securing financial transactions, controlling the creation of new units, and verifying the transfer of assets. Well-known cryptocurrencies such as Bitcoin, Ethereum, and Litecoin operate on decentralized networks, using cryptographic methods to ensure secure transactions and regulate the issuance of new units. Cryptocurrencies function as mediums of exchange, stores of value, or units of account, making possible peer-to-peer transactions without the necessity for intermediaries like banks.

Web 3.0

Web3, short for Web 3.0, signifies the proposed next generation of the internet. This evolution intends to shift the internet from its current state, primarily about information sharing, to a decentralized user-centric platform where individuals exert greater control over their data, and peer-to-peer interactions operate independently of intermediaries.

Web3 aims to deliver a more decentralized, transparent, and user-controlled internet powered by blockchain technology and decentralized network protocols. The vision encompasses applications and platforms that place a premium on privacy, security, and user sovereignty. Web3’s goal is to enable individuals to own and manage their own data, participate in decentralized governance, and engage in peer-to-peer transactions and interactions, all without reliance on centralized entities.

While crypto is specifically related to digital currencies and the underlying cryptographic technologies, Web3 envisions a broader scope, seeking a decentralized internet ecosystem that employs blockchain and additional technologies to enable a more open, secure, and user-centric online experience.

In summary, crypto refers to digital currencies that use cryptography for secure transactions, whereas Web3 represents the concept of a decentralized user-centric internet that relies on blockchain and similar technologies to facilitate peer-to-peer interactions and grant users control over their data. Crypto can be viewed as a subset of the wider Web3 vision.

What is the difference between crypto and blockchain?

Crypto and blockchain, both pivotal elements in the decentralized space, have distinct definitions and purposes:

Crypto: Cryptocurrency boils down to a type of digital currency that utilizes cryptography to secure transactions, control the creation of additional units, and verify asset transfers. Known cryptocurrencies include Bitcoin, Ethereum, and Litecoin, all functioning on decentralized networks. These utilize cryptographic techniques to safeguard transactions and regulate the generation of new units. Cryptocurrencies can be used for peer-to-peer transactions, acting as a medium of exchange, a store of value, or a unit of account, all done without needing a middle-man like a bank.

Blockchain: On the other hand, blockchain acts as a distributed ledger technology, decentralized by nature, and forms the backbone of many cryptocurrencies, Bitcoin and Ethereum being prime examples. It functions as a system for recording and certifying transactions across numerous computers or nodes within a network. Comprising ‘blocks’, the blockchain links together collections of transactions chronologically, secured using cryptographic methods. Each block holds a unique identifier (or hash) of the previous block, creating a chain of blocks. The genius behind blockchain technology lies in its ability to ensure transparency, permanence, and trust all while recording and validating transactions without reliance on a central authority.

In essence, crypto refers to digital currencies that employ cryptography for secure transactions, whereas blockchain is the underlying distributed ledger technology allowing for transparent and tamper-proof transactions. Crypto is a tangible product of the broader blockchain technology.

Can you explain the difference between a public key and a private key in the context of cryptocurrency?

The concepts of public keys, private keys, and blockchain technology play essential roles in cryptocurrency transactions. They not only enable secure transacting but also ensure immutability.

Public Key vs. Private Key in Cryptocurrency

In the context of cryptocurrency, a public key and a private key form parts of the cryptographic principles that secure digital assets. They are instrumental to asymmetric encryption algorithms used in cryptocurrency transactions.

A public key gets derived from a private key and is distributed openly, acting as a receiving address for funds or messages. While it’s public, it cannot unlock or retrieve funds; it merely receives and holds them.

In contrast, a private key is confidential and known only to the owner of the digital assets. It is used to sign off on transactions or messages, thereby confirming ownership and granting access to the associated funds or data. It can somewhat be compared to a PIN for an ATM card.

One of the ingenious operations of this system is the ability for the public key to authenticate the signature of the private key without exposing the private key itself. Essentially, a public key encrypts and verifies, while a private key decrypts and signs off.

What is a blockchain, and how does it ensure security and immutability in cryptocurrency transactions?

A blockchain is a decentralized, distributed digital ledger, recording transactions across a network of computers or nodes. It is essentially made up of a chain of blocks, each containing a collection of transactions.

Several mechanisms within the blockchain structure ensure the security and immutability of cryptocurrency transactions:

Firstly, transactions are grouped into blocks, and these blocks are cryptographically linked to the preceding block, forming a chain. Altering a transaction in a block would necessitate modifications in all subsequent blocks – a computationally and practically infeasible task as the chain lengthens.

Secondly, most blockchain systems use consensus algorithms, such as proof-of-work (PoW) or proof-of-stake (PoS), to validate and add new blocks to the chain. These algorithms make certain that the majority of participants agree on the validity of transactions – a step that shields the ledger from manipulative intents.

Additionally, blockchain makes full use of cryptographic hash functions. Each block in the chain carries its unique hash value, which is determined by the data within the block. Any modification to the block’s data causes the hash value to change, and this discrepancy is easily detected by other nodes in the network.

By integrating decentralization, consensus algorithms, cryptographic hashing, and the chaining of blocks, blockchain technology promisingly offers security and the quality of immutability to cryptocurrency transactions.

How do the proof-of-work and proof-of-stake consensus algorithms vary, and what are their pros and cons?

Proof-of-Work (PoW) and Proof-of-Stake (PoS) serve as two commonly employed consensus algorithms in blockchain networks, each demonstrating unique attributes and implications.

Proof-of-Work (PoW) requires network participants, referred to as miners, to solve intricate mathematical problems to authenticate transactions and incorporate new blocks into the chain. This problem-solving operation necessitates considerable computational power, thereby imposing resource-intensive demands on systems. With PoW, miners successfully crack the mathematical conundrums are rewarded by obtaining freshly minted cryptocurrency.

Key strengths of PoW consist of its robust security framework, which demands that a majority of honest participants control more computational power than malicious ones to preserve the network’s integrity. However, PoW carries limitations, including significant energy consumption and scalability concerns due to the demanding computational requirements.

Contrarily, Proof-of-Stake (PoS) opts for block validators based on the quantity of cryptocurrency tokens participants possess and are willing to “stake” as a guarantee. Validators are selected based on specific criteria, such as the amount staked and the duration the tokens have been in their possession.

PoS surpasses PoW in terms of energy efficiency, as it dispenses with the necessity for exhaustive computational work. Moreover, PoS facilities improved scalability since the validation process is typically faster. Yet, PoS has been critiqued for potentially centralizing control, as it allows wealthier participants to exert greater influence on the consensus process.

Both consensus algorithms bring along their respective trade-offs. Therefore, distinct blockchain networks select the algorithm that they believe best meets their tailored requirements and objectives.

Explain the cryptocurrency mining procedure. What’s its purpose, and how does it impact the entire system?

Crypto-mining is a critical process that ensures the verification and bundling of new transactions into blocks, which are subsequently added to the blockchain in numerous cryptocurrency networks. Miners oversee this operation and occupy a vital role within the broader ecosystem.

Crypto-mining initiates when miners gather unconfirmed transactions across the network. Afterward, they enter a competition to crack a complex mathematical puzzle, calling upon substantial computational power. This problem-solving task is notably resource-intensive and demands extensive computational efforts. The miner who first discovers a legitimate solution broadcasts this to the network.

Once the solution is verified, the miner’s block, which encapsulates the solved puzzle and the validated transactions, becomes a part of the blockchain. To incentivize their commitment, the miner receives freshly created cryptocurrency. This system of rewarding miners with cryptocurrency serves as a major motivator, encouraging them to persist in verifying transactions and fortifying the network.

Beyond adding new blocks to the blockchain, mining contributes substantially to preserving network integrity and security. The computational labors associated with mining deter ill-intended actors from tampering with past transactions or forging illegitimate blocks. Mining consensus mechanisms, such as PoW, ensure the agreement of the majority of participants regarding the validity of transactions, thus preventing the occurrence of double-spending.

Despite the significant role that mining plays, it has been criticized for its high energy consumption and the need for specialized hardware. These limitations have raised concerns about the environmental implications of crypto-mining. Consequently, some blockchain networks are investigating possible alternatives, including PoS, which might mitigate these environmental impact concerns while still preserving network security and integrity.

What do we mean by a smart contract, and how does it support decentralized applications (DApps) on blockchain networks?

A smart contract is a self-executing digital contract that is stored and executed on a blockchain platform.

It consists of predefined rules and conditions, expressed in code, that trigger automatic execution once the specific criteria are achieved. Smart contracts empower decentralized applications (DApps) to function on blockchain platforms.

In comparison to traditional contracts that typically involve intermediaries like lawyers or financial institutions to enforce and verify terms, smart contracts bypass the need for such intermediaries by harnessing the decentralized and transparent properties of blockchain technology.

Smart contracts bestow several benefits on DApps. They facilitate trustless and transparent functioning, as the code is open to public access and its behaviors can be reviewed by any participant on the blockchain. Owing to its unalterability post-deployment, a smart contract ensures immutability and eradicates the probability of fraud or manipulations.

DApps capitalize on smart contracts by employing them as the logic and rules mechanism for their operations. The user-friendly interface of the DApp interacts with the smart contract, enabling users to engage with the application and initiate actions as per the pre-established rules. Thanks to the decentralized nature of blockchain platforms, the execution of smart contracts is impervious to tampering and verifiable by all involved parties.

What are the different types of forks, and how do they impact the network and its users?

At its core, a cryptocurrency fork signifies a split or divergence in the blockchain network. This can result in multiple versions of the blockchain operating simultaneously. The reasons for such a split vary – it could stem from protocol changes, community disputes, or the introduction of innovative features.

Breaking it down, there are two main categories of forks:

Hard Forks: Imagine a complete makeover. A hard fork ushers in significant protocol alterations that make the new blockchain incompatible with its predecessor. This type of fork often mandates users and node operators to update their software to be in sync with the latest network. A consequence? A brand-new cryptocurrency might emerge. Famous examples include Bitcoin Cash (BCH) and Ethereum Classic (ETC).

Soft Forks: Think of this as a subtle upgrade. Soft forks are backwards-compatible. While they do introduce new rules, they remain within the boundaries of the existing ones. Nodes operating older software versions can continue validating transactions, though they might miss out on some fresh features. A prime illustration of a soft fork is Bitcoin’s Segregated Witness (SegWit) implementation.

But why should you care about forks?

Forks can reshape the crypto landscape in multiple ways:

New Cryptocurrencies: As with Bitcoin Cash and Ethereum Classic, forks can birth new digital currencies.
Community Rifts: Forks can sow discord in the community. Different groups may champion opposing visions for the network, leading to potential splits.

User Clarity: Forks can be a tad confusing for everyday users. It’s crucial to be informed about which blockchain version you’re dealing with, and if there are any necessary steps on your part – like updating wallets or deciding between chains.

While forks might seem complex, understanding their nuances can empower you to navigate the crypto space with confidence.

How to Become a Web3 Engineer: A Beginner’s Guide

Savvina Drougouti — Thu, 17 Aug 2023 08:46:40 +0000

Embarking on the journey to become a Web3 Engineer is an exciting one. Web3 refers to the decentralized next-generation internet, which is built on emerging technologies like blockchain, decentralized applications (dApps), and smart contracts. As a Web3 Engineer, you’ll be at the forefront of this new era of internet, shaping its development and revolutionizing the digital landscape. If you want to take your career to new heights, follow our guide on how to become a Web3 Engineer.

5 Effective Tips to Successfully Build Your Personal Brand on LinkedIn

Savvina Drougouti — Sat, 16 Apr 2022 15:01:09 +0000

First impression matters. And given the digital world, the first impression is not made during phone calls or interviews but as people look at your LinkedIn profile. An incomplete or sloppy profile can give the wrong impression to others, seriously sabotaging your efforts. To be discovered and recognized for the right things, it is essential to build your personal brand most effectively. Let’s see right away what you need to know about creating a successful personal brand that will further advance your career.

What is personal branding?

Most often, branding is associated with companies and products, but you can also use the same strategy to stand out and impress a potential employer or hiring specialist. Personal branding is a strategy of creating an image of yourself that fits the story you want to tell. It is how you communicate your best assets, skills, and values. To be truly impactful, your personal brand should represent what makes you a unique professional and a powerful candidate for any job position you want to land.

Tip #1: Complete your LinkedIn profile

In social media, everything is algorithms. LinkedIn’s algorithm favorites professionals who have complete profiles and gives them a boost in search results. With a complete and well-crafted profile, you definitely have a massive advantage over others. The different profile sections allow you to describe your strengths and experience best and add more relevant keywords that make you pop up in searches. Make sure you take the time to fill each section with accurate, relevant information. If you need some inspiration, look at LinkedIn profiles of well-established IT professionals to get some exciting ideas.

Pay attention particularly to the Experience and Licenses & Certifications sections. Rather than just listing your job duties under each entry, detail your achievements. Each bullet point should describe not only what you did in your past positions, but also how you did it and how it impacted your team or company. Make sure you include relevant keywords to show off the used skills and rank higher in the searches.

If you now start your career journey and don't have any working experience, include info for volunteering work, work on personal projects, published blog posts or any other relevant experience. The experience section allows you to add links and media, so use this feature to showcase your accomplishments.

Tip #2: Skills, skills everywhere

As a technical recruiter, the Skills section is one of the first things I check in a profile to see if a professional match the requirements of an open job position. However, I often realize that most people don't mention their skills! LinkedIn allows you to add up to 50 skills, so grab the opportunity and make sure you add all your hard and soft skills.

You can also mention various technologies and tools as keywords within your Experience section as part of your responsibilities. Adding relevant keywords will help you pop up higher in searches, increasing your chance to get an invitation.

Tip #3: Add a suitable profile and cover photo

What everyone sees first when looking at your profile are your profile and cover photos. This is a so important yet neglected detail. Having a great photo of your face makes you identifiable and relatable. People want to know who you are, so it’s essential to ensure your photo represents you in the best way. You don’t need to spend money on getting a professional headshot. Your smartphone has a high-resolution camera to ensure you get a clear picture. Avoid images with a noisy background or inappropriate outfits. And please, don’t use any image where you cropped other people out or a photo from a party, wedding, or your last vacation. Just don’t.

Your outfit should look simple and professional, and your hair should be clean and neat. Then, get in front of a blank wall in a neutral light color (white is the best), face a natural light source (like your window), and look at the camera. It would help if you aimed for your face to take up to 60% of the image once it’s cropped. For optimal results, crop your photo into a 1:1 aspect ratio.

Now, let’s talk about the cover photo or banner. Along with your profile photo, the banner is the first thing someone sees on your profile, so you want to make a good impression. A landscape, a picture that reflects your profession, or a customized banner with words can do the job perfectly. To customize your cover photo, adding info that reflects your skills, services, or even a relevant to your profession quote, you can use a tool like Canva, which offers free, customizable templates for LinkedIn.

Tip #4: Craft a grabbing summary to tell your story

The summary or About section is the place where you can tell your story, free of titles and duties. This is your chance to show off your personality and highlight your biggest achievements. Along with your photos and headline, the summary enhance the first impression you give to others in a way no other section can. It's best to avoid cliché or cheesy terminology like "guru", "master", or "unicorn".

A successful summary format could be the following one:

Grab readers' attention and make them want to keep reading and know more about your exciting personality. Only the first three lines are visible when someone enters your profile, so you need a hook to ensure they click on the "...see more".
Tell people why you do what you do and what you're good at. What is your impact on others, and what are your best achievements?
Call to action: invite people in your network or get them to contact you to know more about how you can help them in their business.

Tip #5: Boost your visibility

You've optimized your profile, so what's next? Creating a top-notch profile is the crucial first step toward building a solid personal brand on LinkedIn, but you can do a lot more to make your profile easy to find and nurture your connections. You need to engage with your network. Here are some ideas for you to boost your visibility and interaction with people on LinkedIn:

Follow

Follow influential companies and people in your target field to stay up-to-date about your professional sphere's trends, discoveries, and events. You can also follow companies you'd love to work with one day so that you see their job posts asap and increase the chances to show up in their recruiters' searches.

Post, Like, Comment

After all, LinkedIn is a social media, so posts, likes, and comments are the best way to interact and engage with your network. Authoring valuable, original posts is one of the most effective ways to boost your visibility.

If you're not into writing, don't worry, you can also engage by liking and commenting on other professionals' posts, elevating your profile's visibility.

Endorse and Recommend

Good team players recognize the contribution of others. By endorsing and recommending former and current co-workers, you can show future colleagues that you are a person who acknowledges your teammates. Recognizing your people's achievements and best assets will deepen your relationship with your network, increasing the likelihood of someone endorsing you in return. It's a win-win situation.

Optimizing your LinkedIn profile is essential for showcasing yourself to recruiters and potential employers. After building your personal brand on LinkedIn, make sure you connect with other industry professionals to create new professional relationships, learn more about a job position you'd want to land, and increase your impact on others.

Complete Form Testing Plan #FunctionalTesting

Savvina Drougouti — Sat, 07 Mar 2020 18:07:06 +0000

Forms are one of the major parts of a website. Forms are used to receive information from the users and interact with them. As testers, we need to make sure that the forms of a website work properly and are easy to use. If a form works well, we can receive valuable information from users, while interaction with them becomes much better. So, what we should check when testing forms?

Layout

Is the form layout easy to understand and logical? Are the labels appropriate for each field? A too complicated form with many fields will discourage a great number of users. A higher submission rate can be achieved when the fields are less and look easy to use.

Fields

A form can consist of different type of fields, such as basic text fields, dropdown select fields, checkboxes, and radio buttons. You should check every field to ensure that you can select the correct option or enter text. Since many forms contain a lot of field types, it’s necessary to test your form under different browsers and devices to make sure they look OK everywhere.

Required* Fields

In most of the cases, forms will include a number of mandatory (required) fields. These fields should be clearly marked as required with an asterisk*. It will be easier for users to distinguish which fields are mandatory to fill and which are optional.

A rule of thumb is to click on the Submit button, before filling in any field. In this way, you will have an immediate look at how the validation behaves and check if the mandatory fields are properly highlighted.

Validation Matters

There are 2 validation types: validation on submit and inline validation.

On submit validation occurs when users submit the form. In this case, any problems will be visible to the user when they click on the Submit button. On the other hand, inline validation occurs when users enter data into the form. Generally, inline validation is considered a better practice for increasing the conversion rates.

The Input Validation

It is very useful there is input validation in some fields, for example in telephone number or email address fields. To prevent the submission of wrong data, a helpful validation message can save the situation, kindly warning the users that they have entered incorrect data. Very specific requirements or generic validation messages can actually discourage the users to submit the form. Additionally, you can check text fields if allow different punctuation marks, as some forms block certain characters due to security reasons.

Validation Messages

Every validation message should be helpful for the users, informing them what the problem is. Check that each validation message describes correctly the error. Pay attention to how the message is written; it should be informative and appropriately worded.

Tab, Tab, Tab

Another factor to check when testing a form is the tab order (an important factor for accessibility). A large number of users use the tab key to go to the next field. Check if there is a correct sequence when tabbing through a form and that the cursor goes to the next field properly. You can also check if completing the whole form is possible when only using the keyboard.

The Tooltips

Many form fields have tooltips to present some helpful information to the users when hovering over an icon or over the field itself. If the form you test has tooltips, make sure that every tooltip message is informative and easy to understand.

Prefilled and Preselected Fields

In some cases, there will be prefilled fields automatically, for example when you are a registered user in an e-shop and want to place an order, certain fields can be already filled, such as name and email address. When you test a similar functionality, check also that preselected or prefilled data are correct.

The Thank you Message

Check if when submitting the form, a thanks page or message is displayed, making clear to the users that the submission was successful. Please note that if the form requires a further action after its submission, for example, to confirm a registration via a confirmation link, there should be a related message, informing the users for the follow-up actions they need to complete. If this is the case, you can also check the follow-up email to ensure if the email is properly sent and the links work correctly.

Go Mobile

Last, but not least, make sure you test your forms using popular devices, iOS, and Android. Filling in a form with a mobile device can be tricky sometimes, especially if there are many fields, including checkboxes and radio buttons. Ensure that all field types behave correctly when mobile and you can easily fill in the form and submit.

At the End

As the last shot, test what happens when a user submits the form. Do you receive an email with all the details of the form? Is the data correctly saved in the database?

If you have completed all the above steps, then you can rest assured you did an excellent form testing!

Congratulations!

Build a simple and working contact form with Bootstrap 4

Savvina Drougouti — Sat, 09 Mar 2019 20:47:48 +0000

In this post you''ll see how you can build a simple yet working form using only HTML5 and Bootstrap classes. No CSS will be necessary!

Using Bootstrap 4 you can build custom components quickly and easily by applying the Bootstrap classes. Did you want to learn how to build modern and responsive components for your projects? Bootstrap makes it easy and this post will show you how to build a simple contact form.

At the end, your contact form should look like this:

https://codepen.io/BlackNina/pen/MxoVqv?editors=1000

1. Setup Bootstrap 4

In order for us to start coding in the bootstrap framework, we first need to link the relevant files to our project so that we can make use of all the default bootstrap styles.

For the beginning, open your text editor, I personally prefer VS Code as I love its powerful extensions, and create a new project. Create files index.html and style.css.

CSS

Include this link in your project between head tags:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

2. Building the contact form

Copy and paste the following code in your index.html file

<section class="resume-section p-4 p-lg-5 text-center" id="contact">
        <div class="my-auto">
          <h2 class="mb-4">< Contact Information ></h2>

          <ul class="fa-ul mb-4 ml-0">
            <li id="mail-address">
<!--               Replace with your email address -->
                <i class="fas fa-envelope-open mr-2 contact-icons"></i
                >youremail@mail.com</a
              >
            </li>
            <li>
              <i class="fas fa-mobile-alt mr-2 contact-icons"></i>+48 888 888
            </li>
            <li>
              <i class="fas fa-map-marker-alt mr-2 contact-icons"></i>Athens, GR
            </li>
          </ul>

          <p>
            ...or leave your message below and I will be back to you as soon as
            possible.
          </p>

          <form
            class="contact-form d-flex flex-column align-items-center"
            action="https://formspree.io/youremail@mail.com"
            method="POST"
          >
            <div class="form-group w-75">
              <input
                type="name"
                class="form-control"
                placeholder="Name"
                name="name"
                required
              />
            </div>
            <div class="form-group w-75">
              <input
                type="email"
                class="form-control"
                placeholder="Email"
                name="name"
                required
              />
            </div>

            <div class="form-group w-75">
              <textarea
                class="form-control"
                type="text"
                placeholder="Message"
                rows="7"
                name="name"
                required
              ></textarea>
            </div>

            <button type="submit" class="btn btn-submit btn-info w-75">Submit</button>
          </form>
        </div>
      </section>

Copy and paste the following script right before the </body> closing tag to use the Font Awesome icons:

<script
      defer
      src="https://use.fontawesome.com/releases/v5.7.2/js/all.js"
      integrity="sha384-0pzryjIRos8mFBWMzSSZApWtPl/5++eIfzYmTgBBmXYdhvxPc+XcFEk+zJwDgWbP"
      crossorigin="anonymous"
    ></script>

As you can see above, I have used Bootstrap utilities to customize some elements instead of using CSS. For example class w-75 sets the width of the form fields to 75%. Class btn-info is responsible for the petrol blue color of our submit button. In fact, we have really many choices among the Bootstrap utilities to customize our elements. without the use of CSS.

You can read more about Bootstrap classes and utilities on its official documentation.

I used Formspree to make the contact form to work. No PHP, JS, or registration needed. You just need to replace youremail@mail.com with your email address to receive the submissions.

Thanks for reading! I hope this helps. If you have any feedback or suggestions, I would be glad to talk to you in the comments.

Feel free to share your favorite VS Code extension. Have fun!

#1 Live Server

Make changes in the code editor, switch to the browser, and refresh to see changes. That's the endless cycle of a developer, but what if your browser would automatically refresh anytime you make changes? That's where Live Server comes in!

It also runs your app on a localhost server. There are some things you can only test when running your app from a server, so this is a nice benefit.

You make changes in your editor and have to refresh to check these changes. True story, isn’t it? Live Server extension comes here to help you see your changes in real time since your browser is refreshed automatically every time you save in VSCode.

#2 Bracket Pair Colorizer

An extension to fall in love for. When you have so many lines of nested code it’s getting pretty tricky to match the brackets. Bracket Pair Colorizer colors matching brackets to make the code much more readable and interesting.

#3 Prettier

Never worry about formatting again! Prettier is here to help you format your code and make it prettier (obviously). It can be configured to format automatically on save.

#4 CSS Peek

CSS Peek is really helpful as it saves much time going back and forth to HTML and CSS files. It’s a pretty fancy extension for developers who don’t like split screen. Hover over a selector within your HTML file and view an image of your CSS code. CSS Peek will also convert ids and class names to hyper links directing you to their definition in the CSS file.

#5 Debugger for Chrome

One of the most popular VS Code extensions for developers, the official debugger for Chrome comes with built-in features to help you debug your Javascript files running in Chrome browser directly from VS Code.

One of the most useful extensions for VS Code, this one will save your day when more than one contributors work on the same repository. History, recent changes, code authorship, blame information and commit searching are some of the best features of this cool extension.

#7 Auto Rename Tag

Do you need to rename an HTML element? With Auto Rename Tag extension you just need to rename either the opening or closing tag and the other one will be automatically renamed. Simply and effectively!

#8 Path Intellisense

If you work on large projects, remembering all directories and file names can be very tricky. This extension will help you, showing autocomplete file names as you start typing a path in the quotations.

#9 Browser Preview

Live Server extension is very cool but this one goes one level further and allows you to open a real browser preview inside your editor that you can debug. No more need to check the browser after making a small change.

#10 One Dark Pro

If you are a dark theme lover, Atom's iconic One Dark theme will become your favorite one. Not surprisingly it's one of the most downloaded themes for VS Code!

How to Write an Effective Bug Report (incl. template)

Savvina Drougouti — Wed, 20 Feb 2019 10:25:08 +0000

Why an effective bug report is necessary?

It's crucially important to write an accurate error report, as in this way you will increase the chances of fixing the bugs you found. Writing an effective bug report is not that difficult, you just need a good pattern and some practice. Remember that a good bug report is the primary responsibility of a successful software tester.

Two main advantages of an effective and accurate report:

- The assigned developer has all the necessary info to start working on it
- Any other tester of the team can then retest it, even if the reporter is not at work

Let's start to see how you can write the best report!

4 general rules for writing an accurate defect (bug) report

Clarity and accuracy: Good writing and communication skills are essential here, as you have to avoid confusions and misunderstandings. Don't miss key points and important information, as this will lead to the slowing down of the development process. It's also quite possible that your report will be neglected and the bug will remain unfixed.
Research before raising a report: When you find a bug, before raising a report, do a quick research for duplicate issues. In many cases, there are long lists with unresolved bug reports, so it's quite possible that a bug is already reported. Make sure that the one you found is not a duplicate of an older issue.
Simplicity: Write your report in a simple and easy-to-understand way. Use short, but meaningful sentences, avoiding too complex explanations and difficult words that can only confuse or mislead the readers.
Create different reports for different bugs: Report every bug as a separate issue. In this way, you can more effectively organize and tracking your issues, closing each issue when the respective bug is fixed. Additionally, reviewing and fixing the issue will be done faster.

How to write a basic bug report (template)

Let's see now in practice! Check this simple report template and adjust according to your needs. In most of the cases, you will be using a bug tracking tool that makes easier the process of writing a defect report, as it will automatically fill some of the information, as the reporter or the issue number. If you don't use such tool, you will probably need to manually write this info.

Description aka Summary: Keep short but informative

Steps To Reproduce: How did you produce this bug? Write down all the steps you followed

Expected result: What is the expected behavior in your case? The expected results are usually predefined in the related requirements.

Actual result: What was actually the behavior in your case? Write the actual behavior of the bug.

Additional, but VERY important information you have to provide:

Credentials of the user(s) with whom you produced a bug
Problem area / URL
Version of the product (if applicable)
The browser you used, especially in cases of design issues
Priority - it depends on the severity of the bug. Most serious bugs should be fixed first.
Severity - show the impact of the bug. There are 5 severity types:

Blocker: No more testing can be done
Critical: Application crashes, there is a loss of data
Major: Major loss of function
Minor: Minor loss of function
Trivial: Small UI errors

Screenshots or / and Screencasts (screen recording). A picture is equal to a thousand words. Take a proper screenshot or screencast and capture this annoying bug in action!

Extra Tips

Report the bug as soon as you find it. If delay, it's possible you forget some important info.
Try to reproduce the problem again. Make sure your bug is reproducible.
Double-check before submitting the report. Read again to find and correct any problems. After all, you are a tester, you should test even your own artifacts!
Take care of the language you use. Don't harass or criticize the developer who made the mistake.

Are you ready to write your best bug reports and increase your productivity? Give it a try!

Top Resume Tips to Land the Job of Your Dreams

Savvina Drougouti — Wed, 20 Feb 2019 09:14:18 +0000

If you were a Recruiter, would you invite yourself to an interview?

It’s not necessary to write an essay or a long list of everything you have ever done since you were a toddler. A recruiter will look at your resume only for a few minutes, so make sure you present the most relevant to the job skills, experience, and achievements. This is your chance to show off your personality, so don’t hesitate to give a personal touch to the resume. Check out the following simple guidelines and make your CV stands out among the others.

Make it Simple, but Effective

A resume should be a short, ideally one page, document designed to present in the best way why you are a good fit for a job position. Be clear yet detail-oriented. Start with your best qualities, such as technical and soft skills, work experience, education. Highlight any certificates and achievements and avoid to write just job titles. Customize your CV for each job you candidate.

Basics of CV Formatting

Since you have only an A4 document to work with, use text and space wisely. Write your contact information at the top of your resume – name, email address, and phone number. Use a 12 pt or 14 pt font for your name and 10 pt or 11 pt for the body. To gain some more space, adjust the margins. It’s preferable to save it as a PDF file.

Spell Check, Double Check

When it comes to a resume, details really matter. If you want to give a professional first impression on your future employer, be sure that you have corrected any grammar errors, spelling mistakes or unclear sentences.

Show your Profiles

Make your resume modern and more informative by adding links to your online profiles, such as LinkedIn, GitHub, StackOverflow or any other relevant account.

Take it Personally

Career Path Change

What if you have taken a different direction and your past working experience seems irrelevant? Do you remember the summary? Focus on it. Place it under your personal details and then add your current professional skills. If you have worked in customer support, take the chance to mention your soft skills, e.g. you can easily work with others. Highlight your major advantages.
