The planning fatigue nobody warns you about in interview prep

There's a kind of fatigue nobody warns you about when you start preparing for coding interviews. It's not from the problems. It's from all the deciding.

I've been at this long enough now that I have all the resources I need, like most of us. LeetCode, Neetcode, YouTube playlists for every pattern, blog posts on every edge case. I've solved a lot. I've learned a lot. And still, every time I'm looking for a new job and need to brush up - the first few days feel weirdly heavy. Not because the material is hard. Because before I can sit down and do anything, I have to figure out what to do.

Blind75 or Neetcode150? DP today or graphs? Did I cover backtracking last week or was that the week before? What's a fair mix of easy and medium for today? Am I behind?

By the time I've answered all that, I've already burned the freshest hour of my morning on logistics.

To be fair, this isn't a huge ask. Anyone serious about grinding should be able to plan their own prep. And on a calm Saturday afternoon, it really isn't a big deal. You sit down, sketch out the week, feel productive about it, move on.

The problem is doing this every single day on top of an actual job. Or college. Or whatever else is filling your week.

Because here's the thing - our brain has two different modes for this kind of work. There's the planning mode, where we decide what to do, sequence things, prioritize. And there's the execution mode, where we're actually solving the problem, recognizing the pattern, debugging our approach.

Both feel productive. Both give us that little dopamine hit. But they pull from the same mental budget, and most of us already have that budget cut in half by the time we sit down for prep.

So we end up spending a chunk of what's left on planning the prep, and then trying to solve mediums with the dregs of our attention. No wonder it gets exhausting. We think it's the LeetCode that's burning us out. It's not the only reason for sure. It's the meta-work around it.

What ended up working for me was almost embarrassingly simple. I stopped treating prep like something I'd fit in when I had energy, and started treating it like a scheduled exam.

The frame I kept in my head was this: imagine you have a coding round at 5 PM tomorrow that you cannot reschedule. There's no retest. You have to show up.

If that were true, you wouldn't be agonizing over which list to follow tonight. You'd just sit down. Your brain would automatically rearrange everything else in the day around that one fixed point.

So I picked a slot - 5 to 7 AM, in my case, though the specific time matters less than the fact that it's locked. The slot was non-negotiable. Whatever I'd decided the night before, or whatever was already queued from the day before, that's what I'd do in the slot.

Two things changed once I did this.

The first was that the slot itself stopped being a decision. I wasn't asking do I have time today, am I tired, should I push it to tomorrow. The only question was what am I doing in the slot. That alone removed a huge amount of daily friction.

The second was that my interviews started feeling different. When you're in the rhythm consistently - brushing up concepts, taking on problems, revising, learning more, locking it in - your brain just works differently in the room. Edge cases jump out faster. You think laterally instead of trying to remember the specific trick. You're more relaxed because the prep isn't this anxious thing you're cramming, it's just something you've been doing.

Being "interview-ready" stopped being a state I had to panic-cram into a few weeks before applying. It became something I just was, most of the time. And the moment I needed to ramp up for a specific company or role, I had a base to ramp from.

I started building grind50 somewhere along the way, mostly to take this whole approach off my own plate. The idea was to remove the planning entirely - you get a curated daily set, the patterns you learned weeks ago come back for revision before you start forgetting them, and the time block is treated as a commitment you show up to. The only thing left is the actual work.

I'll write more about how it's built and what I learned along the way in a follow-up.

What I'm more curious about, though, is whether the planning fatigue thing resonates at all. Is that the part that drains you, or is the bigger drag something else - motivation, retention, knowing if you're improving, something I haven't named?

Do tell if any of this lands. Curious how it actually feels for you.
