The recruiter sent many emails to students at my school. The first round was a short case (20 min) on campus. Next, they asked for a easy, basic math and verbal skills online test. Finally, I had a final round in Richmond at their headquarters. You get 2 case interviews and 1 behavioral. Each interview is 45 minutes long. You have plenty of time to ask questions. Get them to like you. If they think you're good, you'll get a fourth interview that day.
