There was an on campus case interview which wasn't too hard,. very similar to the practice one on their website. Then they flew/paid for gas for you to go to their office for a "super day" kind of thing. Once there we had to do 3 case interviews and 1 behavioral interview which was the easiest thing ever
Interview questions [1]
Question 1
all of the questions were straightforward if you are good at math. feel free to ask them how credit cards (or whatever the subject of the question is) actually work and they're happy to explain. as long as you know how to do math once they tell you how the problem is structured you'll do fiine
The process took 2 days. I interviewed at Capital One (Washington, DC) in Mar 2011
Interview
First I took a math test, reading test, and work habits test online. Second I had a case interview on campus. That went well. After that, they flew me to the D.C. HQ for more interviewing. They put me up the night before. On the interview day, I had two case interviews and a personality interview. They then asked me to do an extra case interview. I received no offer, even though it seemed to go well.
I applied through college or university. The process took 4 weeks. I interviewed at Capital One (Richmond, VA) in Mar 2011
Interview
First round case interview on campus. Then invited to Richmond for second round, which consisted of two cases (~45 min each) and one behavioral. Same interview process as full time prospects. Put us up in a nice hotel, took care of flights, etc. which was definitely a plus. Seemed like good company culture. Three of my interviewers were very cooperative, but the fourth was quite arrogant.
