I applied online. The process took 1+ week. I interviewed at Jane Street (London, England) in Nov 2017
Interview
The questions were mostly probability related. Quite easy, but I got really nervous and did not answer all of them correctly. The guy interviewing me was pretty friendly.

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.
