I applied online. I interviewed at Jane Street (Sydney) in Aug 2016
Interview
Applied online and got a reply the next day asking for a date for a phone interview. The interview itself took about 25 minutes over the phone. It was very difficult, they asked many hard probability questions, and didn't provide any help. The interviewer was very kind though and was pleasant to talk to.

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.
