I applied online. The process took 2 weeks. I interviewed at Citadel (New York, NY) in Sept 2023
Interview
OA, technical screen, 3 more technical screens, and then team matching. Most of the questions were medium/hard LC with some low level systems questions too. Overall fast and good communication from the HR team.
Online assessment with 3 coding questions on bfs and stacks etc.
First round on a simple coding question with some basic CS questions on top of it and also asked many CV questions and motivations
Did not proceed after this round
OA then phone interview, discussed about experience, coding rounds, and some open ended questions afterwards. The last 5 - 10 mins was for interviewee to ask questions back. Didn't pass this round :(
I had an HR screen where they asked about my experience at my previous company and to prepare for C++ to talk with the hiring manager. They asked about why I got laid off at my previous company.
