I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in Oct 2015
Interview
Received an invitation of phone interview within 1 week. Asked three probability problems. No financial background needed. Not allowed to use pen or calculators. The first one is 10 people in the room, shake hands with each other, how many total hand shakes are there. My recommendation is to do as many probability problems as you can before the interview.

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.
