Capital One interview questions

This was the first round case interview. Spent a few minutes discussing the position/my qualifications then got straight into the case. Much more numbers based rather than strategy. Question was Subway owner adopting $5 foot long promotion. Needed to use weighted average. Huge plus is they'll let you use a calculator. Although the math was simple and straight forward, it definitely helps if you get nervous. Got a second round in a few weeks.
