I applied through college or university. The process took 2 weeks. I interviewed at Jane Street in Dec 2011
Interview
The interview lasted four rounds before I was told I was no longer being considered. First two rounds were in-person at my university and in the surrounding area, while the third and fourth rounds were by phone. First two rounds were quicker questions about probability and estimation, while the later two went more in depth on specific problems.

Question 1
You're playing a game with a deck of cards, where you draw the top two cards from the deck. You win if both are red or both are black.

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.
