I applied online. The process took 2 weeks. I interviewed at Jane Street in Sept 2014
Interview
chaotic. after half an hour of waiting I wrote them an email and my interview was rescheduled. prepare a good phone for the phone interview. the interviewer sometimes does not seem to pay attention to you and a misunderstanding can lead to 10 minutes wasted on solving a different problem. since all the interview questions can be found on this web page, it seems that in the first interview, they measure how well informed you are about the opportunities to beat the system.
Interview questions [1]
Question 1
I did not know about glassdoor, so the most unexpected was evaluation of my confidence (in %) in my answers. the only one that I struggled with (without pen and paper) was the car betting game. after the interview I googled the questions and they are all on this site.

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.
