I applied online. I interviewed at Citadel (London, England) in Jan 2026
Interview
OA, had to exchange dozen of emails to receive it then 45min first round. Ended up in a rejection although I solved the two problems one in cpp and the other in python
First did OA and only passed 1/2 questions, where the first one was probably a leetcode medium and the second one was an easy. Then got first round interview, which I havent done yet.
Interview questions [1]
Question 1
1st OA questions was I think a search problem and 2nd OA question was a dp problem.
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.
