Applied through campus recruiter, was contacted several weeks later for a superday. Consisted of three 30 minute interviews with two interviewers per session. It was very enjoyable. You will want to walk in knowing exactly what the position you are applying for does. Obviously you are expected to be able to show them that you have a good understanding of how macroeconomics work as well, i showed them this through my stock pitch and explaining how the current market conditions would effect my returns.
