I applied online. The process took 1 day. I interviewed at Jane Street in Mar 2012
Interview
This is the first round interview. It lasted for about 30 minutes. All the questions are about mental math, with simple maths like addition and multiplication to more difficult conditional probability questions. To prepare for the interview, one should practice those previous questions. During the interview, you are required to show how you arrived at the answer.

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.
