I first interviewed for this job on campus. There was a 30-minute case-only interview; it had relatively easy math involved, and was about how to fundraise for an organization given the cost of the fundraisers and the expected donations from different populations. The second/final round was a Power Day at Capital One's HQ in McLean. There was a lot of preparation options available, including conference calls and a guide for the interview. The interview itself was two cases and one product interview. The case interviews were both about the break-even costs of implementing different pricing/fee structures for credit cards. The product interview involved three different parts. The first was 10 ways to improve a trash can. The second was to choose a product/service I liked and explain the business model. The third was to explain how Amazon would launch their drone delivery service. Overall, the interview process was good, but I was thrown off a bit in the end because they specifically told me that the cases would not include a certain thing, but then the cases were basically all about that thing they said it would not include. The math was much more difficult (to me) than in the preparation material. They were, however, helpful in preparing otherwise and good at contacting about anything.
