[Beta] I built a pattern-recognition trainer for coding interviews because I kept freezing on problems I already knew how to solve
I have been writing software for ten years and I still stalled on interview problems. Not on the code. On the first ten minutes, working out what the problem even was.
Every course I bought put the pattern in the heading. "Sliding window: maximum sum subarray." You read it already knowing the answer.
Then the interview hands you the same problem with the heading gone and you sit there listing everything it might be.
So I built the exercise that was missing, for me.
Problems with the label removed, ninety seconds each, and you answer with the pattern, the signals that gave it away, and the target complexity.
After ten of those it shows you a confusion matrix: which patterns you swap for which, and how often. Mine said sliding window for two pointers, eleven times. I had no idea.
It works on me. That is the only evidence I have, which is why I am here.
Free test first, no account, fifteen problems, about seven minutes: https://algopath.pro/placement
If it lands for you, I am taking beta testers. Sign up before end of the August.
What I want back is honest feedback: which questions felt ambiguous, where you got bored, what you expected to be there and was not.
