I applied through college or university. The process took 1 day. I interviewed at Jane Street (New York, NY) in Sep 2011
Interview
Very interesting interview experience. The trader I talked to was also a graduate of my university, and very laid-back. Very strong and loyal culture, but it sounds like an extremely intense environment. The interview consisted of like 5 minutes "fit," but it wasn't forced at all, mostly conversation. The rest of the interview was straight-up quantitative brainteasers and probability. Took me forever to multiple 27 times 37.. be prepared with your mental math for sure.

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.
