Citadel

As you'd expect for a hedge fund, there were detailed, multi-step interviews with 4 technical rounds via Zoom, then in person. Interviews were all done by the team that they were hiring into. The last step was with a senior business user.

First round technical interview via Zoom: * Introduction of my current and previous work. * They introduced the job duties. * Technical questions on basic hardware computation. The process lasted around one hour.

The process was set up entirely on Zoom during this hard time. Interviewers are from Hong Kong, Chicago, and Sydney. They are very friendly, so don't worry if you can't answer all the questions completely.
