I applied online. I interviewed at Jane Street (New York, NY) in Aug 2017
Interview
Lot of probability questions and quantitative concept checks. Got to second round phone screen, but messed up on questions that were not too diff. Would recommend this company, make sure to have a decent handle on probability and expectation beforehand though

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.
