I applied online. The process took 4 weeks. I interviewed at Jane Street (Berkeley, CA) in Sept 2022
Interview
Math Puzzles and brainteasers for the first interview. The second interview is about coding questions in any language you choose. It is over the phone and with a coderpad software.
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.
