Got the Online Assesment about a week after applying to the job req. The process itself is pretty quick, as the email itself said too. Was supposed to be followed up by phone interview.
Interview questions [1]
Question 1
There were 2 questions for 2 hours, both were difficult and I got TLE for a lot of test cases.
I applied through college or university. I interviewed at IMC Trading (Chicago, IL)
Interview
for online assessment, there was a question about calculating info from an order book. helps if you know how one works beforehand. only one question and coding preferred in C++ or java.
one technical round and one hr round. technical round was moderately hard. hr round was about your personality, asking about general questions to check if you fit in their workspace.
