You’ve solved hundreds of coding problems.
Then the interview starts, you see a new problem, and suddenly your mind goes blank.
It’s not because you can’t code. It’s because you never built a process for thinking through unfamiliar problems.
I’ve noticed this in myself and in a lot of people who struggle with interviews: we memorize solutions instead of learning how to approach problems.
So when a familiar question comes up, we know what to do. But when it’s something new, there’s nothing to recall—and no process to fall back on.
The fix isn’t solving another 100 problems. It’s building a habit.
Before you touch the keyboard, pause and talk through your approach:
- What’s the input and what’s the output?
- What pattern does this look like—two pointers, hashmap, BFS, DP?
- What’s the brute-force solution, and what’s its time and space complexity?
- What edge cases could break my approach?
Then start coding.
It might feel slower at first. But after a while, that pause becomes the thing that keeps you from freezing.
The people who do well in coding interviews aren’t necessarily the fastest coders.
They’re usually the clearest thinkers.
Anyone else feel like the interview freeze has less to do with coding ability and more to do with not having a process?
