Capital One interview questions

Applied for position through university career center and was invited for a first round 30-min case interview. Case was easy, profitability analysis of credit card for premium customers. All data was provided on a piece of paper, did not have to probe for more quantitative information. First layer involved simple profitability analysis to find profit of credit card. Second layer involved changing a few parameters (credit line), and analysis what other factors would change (number of customers, card utilization), and then find out what the new utilization would have to be for profit to remain same. No behavioral aspect, case took up most of the 30 mins.
