I applied through campus recruiting and got an interview for the Financial Intern Program. The interview lasted exactly one hour and the entire time was a case interview. They walk you through a hypothetical case. This case is different from most because there is a right answer and it is possible to get it. You get a calculator. They give you revenue, and costs and ask you to find profit. Once you get that, the slightly change the situation and you have to adapt your answer to the situation and rework your answer. You have to be flexible and understand the concepts.
