I applied online. The process took 2 weeks. I interviewed at IMC Trading
Interview
First online problem solving interview, answering prerecorded questions. Second round was a phone call asking behavioral/personality/motivation type questions. Third interview online with traders where there were two sections taking about 20 minutes each. I didn't think they were too difficult but was very nervous so didn't perform well. Going in with a cool head would be my best advice.
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
