I applied through college or university. The process took 1 day. I interviewed at Jane Street in Feb 2010
Interview
This was 2nd round phone interview. I got a couple of basic probability questions and EV. Then, I got a hard question where I was asked to estimate my confidence that I'd been done in X minutes.

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.
