Capital One Business Analyst Intern interview questions

Met them at our school's career fair (they're our biggest recruiter and our school is THEIR biggest recruiter) and they were really friendly and nice. Dropped off a resume with them and got invited back to interview a few weeks later. Only a 20ish min interview that was pretty straightforward and easy. Found out a week later that I was invited back to a final round interview in McLean, VA. Final rounds consisted of 2 case and 1 behavioral, each 45 mins long. The cases were of medium-hard difficulty, but I stumbled because the interview was unfriendly and this was my first formal case interview ever. Found out a week or so later that I didn't get it because they wanted to see stronger performance for my cases. Overall the people were nice and really friendly. Most of them were pretty young (under 35) and talkative/helpful.
