Capital One Business Analyst interview questions

it was a first round campus interview, but it was a case interview. Total time 30 mins. The interviewer is quite nice. He'll guide you through the whole interview by asking questions. The case is simple about exploring online tools to capture customers. you need to calculte some numbers. they'll provide calculators, work sheet and pen.

Got the interview from campus recruiting. Interview consisted of introducing myself/telling story and was followed by a case. I answered the case perfectly until the last question which I messed up. The case involved credit card incentives and finding the equilibrium between interchange charge revenue and financing charges revenue on different credit card balances. Easy questions but got thrown off. They never contacted me again.
