I applied online. The process took 2+ months. I interviewed at Citadel (London, England) in Nov 2018
Interview
The process consisted of 3 stages - coding challenge, technical phone interview and an on-site. Over the application process there were only technical questions, I didn't have any HR/behavioural interviews. On-site took approximately 4 hours.
I waited around 4 weeks for a response after the on-site despite being informed that a response will come in 2 weeks after the interview.

Question 1
First two stages were coding mostly, whereas the on-site had a lot of maths as well.
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.

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.
