I applied through college or university. The process took 4 weeks. I interviewed at Jane Street
Interview
I applied through my university. I got a reply scheduling an interview on campus. The interview was 30 minutes of quick mental math and probability questions. The questions were not difficult but you have to be able to answer quickly and walk the interviewer through the problem without hesitation. They did not ask any behavioral questions or anything about my resume.

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.
