I applied online. The process took 3 weeks. I interviewed at Citadel (New York, NY) in Oct 2025
Interview
The interview process was straightforward and was not too hard. I first got sent a HireVue to complete with basic behavioral questions, then two leetcode style basic coding questions. Then they followed up with a video interview.
First round 45 mins total with short behavior and technical. I had one question, which was a class design question using heap. Solved question in time but did not hear back.
OA, one technical round, technical superday (3 interviews), leadership call rounds (mix of technical and behavioral qs, typically 2 ro more calls). did not pass the leadership round, very high variance.
