One general fit 30 minute interview with an associate where I had to state my preferences for which office I would like to work for. Questions were basic "tell me a time when..." and then a more focused roleplaying question at the end. After first round I was contacted for a second round about a week later by the office I ranked 1st for my geography preference. Second round was 3 hours with 4 interviews and one informational panel with analysts. It was entirely fit questions, and a lot of the interviewers asked similar things. Panel was ungraded, just a chance to get to know more of the office. 2 weeks later I received my offer.

Applied in October didn't hear back till March. Great, young people that are extremely nice. Interviews weren't overly difficult, focused more on behavioral questions. Was asked a lot of questions on teamwork and what I would personally bring to the company.
