I applied online. The process took 4 weeks. I interviewed at Jane Street
Interview
Was first asked to complete a Hackerrank exam and then had a phone call interview. Though the interviewer was friendly he wanted a lot of details about thought process and verbally describing my math and equations which isn't always the easiest.
Interview questions [1]
Question 1
The phone interviewer asked me two brainteaser/probability questions. One was a typical probability of picking a matching pair of socks if you have a certain number of similar socks in a drawer.
There was a few phone interviews that involved probability and game theory questions. Before a final round interview in hong kong. Interviewers are very nice best to describe your thought process

Question 1
If you roll a dice and receive that amount in dollars but have the option of rerolling up to two times, how much would you like to pay to play this game?
Jane Street’s interview process is fast-paced, multi-round (But if you have a deadline they will react accordingly) , and deeply quantitative: mental math, probability puzzles, game theory..., and conversational talk just before you start doing the problems

Question 1
Some basic probability questions (more like brainteasers) involving expected values and markov chains. You should brush up on the greenbook and be comfortable with n-sided dice and strategies involving dice in general.
