I applied online. The process took 4 weeks. I interviewed at Jane Street (London, England) in Apr 2023
Interview
I went through three phone interviews with quite hard probability questions. The interviewer always helped get you to an answer if you struggled and they were always very nice, it felt like you were solving a problem together.

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.
