The process took 1 day. I interviewed at Jane Street (London, England) in May 2012
Interview
Simple questions really. Haven 't prepared well and outcome was a bit disastrous.
The interviewer was quite friendly and helpful with the process but the questions
depend on how well you perform, e.g., if you stuck on a simple question don t expect
to ask you subsequently a hard one. They gradually increase the level of complexity.

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.
