I applied online. I interviewed at Jane Street in Jan 2017
Interview
Asked various brain teasers, some tough questions on probability, some discrete math problems as well. Probability questions were difficult, focused a lot on conditional probability and dependent random variables. Interviewer was very nice, patient and walked through the solutions at the end.
Interview questions [1]
Question 1
What is the largest number I can obtain such that the product of the digits of the number is 32?
Very fun process, need to explain your thinking clearly and cleanly, interviewers were nice for all interviews as well. I would recommend working on math and probability questions prior to doing the interview,
The process began with serveral online tests for maths and logic. They gave a personal interview to get to know the candidate better and evaluate fit for the company/role, then held a technical interview covering maths and logic problems.
Fun and filled with unexpected questions. The questions rely on fast thinking and fast calculations, and sometimes intuition because there is no sufficient time for me to work through the whole problem.
