Submitted resume online, got an email back the next day setting up a phone interview. Interview itself was laid back, but extremely mathematical and difficult. Started off with some mental math questions then quickly progressed into difficult probability and reasoning problems. The interviewer was extremely friendly and helped walk through certain problems with me.

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
