Got an OA and a video interview, OA is a very easy question and video interview are short questions and needed to answer in 30s. There are only few questions related to algorithm, which makes me quite disappointed.
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.
