I applied online. I interviewed at Jane Street in Mar 2017
Interview
Standard Trading interview. Had an online test, then moved to phone interview with a trader. Very little behavioral, jumped right into the technical. Took close to 50 mins, which was lot longer than I had expected.
Interview questions [1]
Question 1
The first player chose an integer between 1-30. The second player picks a different one. After that, a random integer (x) between 1-30 will be generated. The player whose number is closer to x get paid x dollars.

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.
