Preparing for your Poshmark coding interview

Poshmark interviews focus heavily on array, matrix, simulation problems. If you're short on time, these are the categories to prioritize. The problems on this page are sorted by frequency, so start from the top and work your way down.

Beyond solving problems, practice explaining your approach. Poshmark interviewers care about your thought process - how you break down a problem, consider edge cases, and evaluate tradeoffs between solutions. A clean O(n) solution you can explain clearly beats an O(log n) solution you can't articulate.
