I applied online. The process took 3 weeks. I interviewed at Jane Street (New York, NY) in Apr 2022
Interview
Series of over-the-phone calls with traders. Time spent on technical questions: probability, brainteasers. Each call with increasing difficulty. Time at the end of the call for a brief question or two.

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.
