I applied online. The process took 4 weeks. I interviewed at IMC Trading (Chicago, IL) in Nov 2023
Interview
Only had the initial online assessment. The assesment had brain teaser, math and statistics questions. You could use pen and paper for it. I believe it was 15 questions in 45 minutes
I can only really recall the penultimate round, which was with a recruiter who gave a mixture of behavioural/motivational questions and then some sort of stand-alone probability questions. Generally a good experience.
Interview questions [1]
Question 1
Standard behavioural/motivational questions, and then some basic probability questions around dice rolling, I believe.
Generally very nice, a lot of probability and expectation problem. First it was a OA and then 2 rounds with traders. Also a betting game on game results. Final round was with two trader and a bit harder.
HR round with 1 technical EV question, second round was a brainteaser and sports betting game with odds, final round was game theory question and another question related to the order book
