Capital One interview questions

Applied online and got contacted by a recruiter. Did some online testing (verbal / numerical) then got flown out for an onsite interview. Interview was difficult but not impossible. The day is broken up into 2 cases 1 behavioral and a recheck of your online testing. They then take you around their campus and you talk to people that work there. Don't worry about the behavioral interview, its just STAR method and I'm pretty sure its designed to just calm you down in between the case interviews. The cases vary but I got one about direct mail vs phone calling to contact new customers for a capital one credit card. The interviewer was a bit tricky and made me second guess stuff, but its not hard to handle. The last question on that case was how to decide between direct mail and phone calling when there's a limited budget and audience. You have to write an equation that links the 2 variables and then explain it to him. The other case was about dominos pizza and how they're considering changing from a free pizza if delivered late model to a discounted pizza if delivered late model. Really straight forward, don't over think this one and you should be fine. You have to calculate how much % demand and supply changes to make the 2 systems equal. Overall the company seems great, and offers a lot of benefits. The interview process are hard, but I was told by a VP there that if you don't get it, you can just apply again in a few months and you go thru the process all over again.
