The first case interview was analytical. It was basic math but the correct questions needed to be asked by me in order to come up with the correct revenue - estimate. Another case dealt with a domestic company looking to expand globally. You should be up to date on current economic news. The final case interview was less about problem solving and more about how you would handle difficult team environments and difficult clients. The confirming interview more of a laid back conversation with basic behavioral questions mixed in to help drive the conversation.
