The first round of interviews is on campus. They do a case study-- consulting style--- and a behavor type interview. The case study is pretty straight forward and is less theoretical than a consulting firm might give. They'll ask you actual industry related questions and you'll need to do some math and analysis to figure it out. The behavior based interview is also really easy, they're mostly looking to see if you fit in. The second round is just 3 more behavior based interviews.
