Initally it was a one on one interview at my school with an associate. Then I got a call back to have an interview in New York with several different associates. The culture was very relaxed. Everyone was dressed in business casual and some people were even in jeans. Some of the interviewers were very nice and easy to talk to while some asked more technical questions. There was a general run through of the resume. One interviewer asked me to teach him a subject.
