I applied online. The process took 2 weeks. I interviewed at Citadel (Chicago, IL) in Oct 2018
Interview
Phone call, followed by onsite. Phone call had nothing technical. Onsite was brutal. 6 people interviewed me, each for about an hour. They asked a little bit about research but mostly focused on technical problems. Last round is with the guy who manages the team.
