The process took 5 weeks. I interviewed at Jane Street in May 2012
Interview
Four phone interviews. Quality of the interviewers varied: Two were pretty reasonable. The other two seemed not to care very much, and I got the impression that they weren't paying attention to the interview. (One flat out told me that he was going to keep working on something at his trading desk *during the interview*.)
The questions were very similar to the ones posted here. One thing I'd say is that accuracy matters; They seem to really care about the actual arithmetic in addition to the conceptual solution.

Question 1
The one posted several times here, about the bus stopping and letting people off.
I interviewed at Jane Street (London, England) in Jan 2026
Interview

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.
