Interview
I applied online, and they called back to set up a phone interview. The phone interview took about 40 minutes, and was done without any online resources, i.e. the interview was by voice, although I was allowed to write on a scratch sheet of paper. The interviewer asked me two questions, the first being somewhat difficult (below), and the second being reasonable.

I applied through university. I interviewed at Jane Street
Interview
Only made it to phone interview, interviewer is nice and professional. Should have been more prepared to not waste the opportunity. Got interview through campus recruitment. Never knew this firm existed until I applied.
30 min - 1 hour phone interview. The interviewer asked 2 brainteaser/ probability questions that were reasonable in difficulty (not crazy). Interviewer was kind and helps if you make a silly mistake.
