Two interviews were strictly problem solving questions, one was a mix of behavioral and problem solving questions, and the third was strictly behavioral questions. For the problem solving questions I was asked "what country should business unit XX expand to," "who will win in tv, apple or google," etc. In each of the questions there was a focus on what data I would need to make my decision. Once I answered this part of the question, I was often asked "what else" would you need. My advice is to just keep throwing ideas out there and not worry about being wrong. I think you need to prove that you can keep up with them and not be intimidated by their style.
