9 Rounds total, did not make it all the way. Interviewers and recruiters were nice and flexible with schedule although the process moved quickly about 3weeks to do multiple rounds.
I applied through a recruiter. The process took 2 months. I interviewed at Citadel Securities (New York, NY) in Mar 2023
Interview
Two behavioral phone screens followed by a three hour long case coding exercise. Then an hour to present the code to the manager and another analyst. Final round in the office with mostly behavioral questions.
