I applied through university. The process took 2 weeks. I interviewed at IMC Trading (Chicago, IL) in Oct 2016
Interview
I interview first round on campus with a hr, it was a very intuitive question, got email about final round 2 days later and final round was scheduled after a week.
Surprisingly almost all the questions are about finance, so if you are looking for quantitative role with a cs/math background this might not be a good choice. I have two final round interviewers with Econ/finance background and I felt very hard to communicate with them.
Tough, asked me numerous questions about probability, statistics and also asked me numerous questions about options. questions ranged from numerical to also behavioural (stuff about risk). how i approached life
First some technical tests consisted of probability questions, then HR with easy probability and mostly behavioral questions. After that the first technical and finally in-house day with all rounds again: technical, trading, HR and some informal talk.
