Citadel Securities Software Engineer interview experience

New York, NYPosted Oct 2025 · Candidate report, summarized by Dataford

I took an online candidate assessment with two questions, and both had hard restrictions on time limits.

The limits were tight enough that I needed efficient solutions just to get through test cases.

The topics included a matrix sliding window-style problem and then a dynamic programming question. It felt like they were testing whether I could quickly identify the right pattern and implement under pressure, not just solve eventually.

I didn’t end up with an offer. The main impression was that the round was tuned for efficiency and speed of thinking—if the approach wasn’t immediately right, the time restrictions made it unforgiving.
