I applied online. The process took 4 weeks. I interviewed at Jane Street (New York, NY) in Oct 2017
Interview
I had three phone screens and then an onsite. The phone interviews were about 45 minutes to an hour long about statistics and probability. The onsite is some betting games with poker chips.

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.
