I applied online. The process took 4 weeks. I interviewed at Jane Street (Hong Kong) in Jul 2024
Interview
Failed my third round of interview. Each interview was a math question, involving 2 way discussion with the interviewer. gets harder each round. virtual call with the intervewier. one of them did not on the camera which makes it slightly unpleasant. the others were friendly in facilitating their discussion
Interview questions [1]
Question 1
1 math question that is built upon as the interview progresses.
They tend to examine the logical thinkers that can communicate clearly and concisely, and some problem-solving exercises intended to explore how you gather and apply new information, very different from other tech companies' interviews.
Initial application and online assessment. Had a first round behavioral interview where they asked me about myself, my experiences, and a couple of brain teasers. The interviewer was very nice.
Phone interviews (at least 3) - questions were of mixed difficulty (some pretty hard) but the interviewers were friendly and they gave helpful hints. Kind of fun - review probability and game-type questions.
