I applied through college or university. The process took 1 day. I interviewed at Jane Street in Feb 2011
Interview
Got the interview after applying through a campus recruitment program. The interview started with some general background questions, followed by simple mental math questions and probability questions. The interviewer seemed very friendly. It appears to me that they are looking for people who could do calculation very fast and who have basic understanding about probability theory. At the end of the interview, the interviewer provided an opportunity for me to ask a few questions about the company.

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.
