I applied online. The process took 8 weeks. I interviewed at Jane Street (New York, NY) in Aug 2017
Interview
Phone Interview. Overall the people were very pleasant/polite throughout the process, although you can tell the culture is extremely nerdy (not a bad thing) and that there is a strong emphasis on second order knowledge / non-overconfidence.

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.
