I applied online. The process took 3 weeks. I interviewed at Jane Street (Edinburgh, Scotland) in July 2015
Interview
I got an email to set up a phone interview. The phone interview lasted about 15 min and it was about solving mathematical problems with clever reasoning rather than heavy calculations. The questions are meant to see the way you think since you are not allowed to use calculator nor pen and paper, thus you have to explain your reasoning. The interviewer was helpful and explained clearly all the questions.

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.
