I applied online. The process took 1+ week. I interviewed at Citadel (New York, NY) in Apr 2019
Interview
I applied for the Rotational Program. I was told that has moved forward after accomplished an Online Assessment. The interviewer was nice and give me some hints to think through the question. He asked some basic python knowledge and then we move the coderpad for the coding problem.
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.
