I applied through a recruiter. The process took 1 day. I interviewed at IMC Trading (Chicago, IL) in Mar 2012

Interview was one on one. A bit like pinball, he talked, I talked, he talked, I talked.
Their office is very new and updated.
Be prepared to answer job related questions and do not be afraid of being blunt.
