I applied online. The process took 1+ week. I interviewed at Jane Street (Hong Kong) in Nov 2015
Interview
very good. the questions are very basic and you can find all of them in the glassdoor. but I was very nervous at that time, so I did not answer very well. 5 questions in total, such as throw a fair die with 6 faces, the expected number of times until 2 consecutive 6 come out

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.
