I applied through a recruiter. The process took 4 weeks. I interviewed at Citadel (New York, NY) in Feb 2016
Interview
I had Two phone interviews. One with the manager and second with his manager and last was HR round.
The Recruiters were very friendly, easy to talk to and always kept me updated. I reached out with various questions and they answered them nicely.
