OA coding challenge. I had to solve one question in 90 mins. The question was medium level and took almost 70-80 mins to solve. Although the question looks lengthy but it is doable.
I applied through 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.
Coding Challenge, Recruiter Phone Screen, Project Interview, Onsite. Coding Challenge was definitely on the challenging side of those I've taken. They dive deep into your past & current experiences for project interview. Onsite was challenging -- a long problem statement.
