Smarkets Software Developer interview questions

First was recruiter screening, just questions on your current situation and what you're looking for. The second stage was two leetcode style questions (1 easy & 1 easy/medium). The third stage was a backend-style question. The question itself was straightforward but you needed to get the optimal solution within the given time (without wasting time). I made a silly mistake early on (wasting time) but still got 14/15 test cases passed but wasn't good enough. Everyone was very friendly, communicative, quick to respond and most importantly gave feedback after the interviews.

All very standard. Phone screen, codility, 2 in person interviews. Final interview was with CEO who has a bit of a reputation. Was screened for not being a good culture fit (whatever that means).
