The interview process consists of 3 stages Online Round (consisting of questions from Data structures and algos) + Behavioural (general questions about you/why join the team) + Technical Interview (implement a stack data structure for eg)
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.
