I applied through college or university. The process took 1 day. I interviewed at Jane Street (New York, NY) in Jan 2011
Interview
The interviewer was cordial, but the interview questions were very technical. The first round interview consisted of mental mathematics -- pen and paper were not allowed. I could tell that the interviewer was not happy with my performance (never having trained for mental maths) and I was not invited back for a second round of interviews.

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.
