The process took 1 day. I interviewed at Jane Street in Feb 2011
Interview
The 30 min interview consisted almost completely of mental math/probability questions. I did horribly, but the interviewer was very nice and told me to apply again in subsequent years. A lot of the questions were not terribly difficult, but I would need a piece of paper, so getting a wrong answer repeatedly was rather discouraging. Also, if I didn't know how to do a problem on the spot, the interviewer didn't move on; he just let me work it out until it was very, very obvious how wrong I was.
Two or three probability/statistics brain teasers/problems that you have to solve. Topics include Markov Chains, EV, decision/game theory, branching processes, gambler's ruin, best decisions, optimisation. Interview with an actual quant.
CV submission, followed by online assessment (fairly easy 10 questions), then first round zoom interview. One interviewer, one hour interview. 2 problem solving questions asked with multiple follow ups for each one.
Interview questions [1]
Question 1
Design an algorithm for when to replace a car at a car rental company
Was asked a general mathematical problem solving question - no personal details or anything else was discussed, was overall relatively easy and I imagine a fair amount of support would be offered if struggling.
