I applied online. The process took 4 weeks. I interviewed at Capital One (Plano, TX) in Mar 2015
Interview
Efficient and thorough. They are definitely looking for nearly flawless candidates. Two case-style questions that involved working through profit/loss maximizing and minimizing. Two "behavioral" sessions which are more conversational about your background and motivations. I was not given an offer, nor told why I wasn't a good fit. I felt good about my background, case answers, and overall discussion with the team members. I suspect the position was ultimately given to someone less expensive or that was local as I would have needed a relocation package.
Interview questions [1]
Question 1
Determine average daily cost or profit, then tweak the initial set of variables for new scenarios and finally determine a break even point.
Started with an OA, and then proceeded to data challenge, and afterwards it was Power Day which had 4 rounds of interview. 2 of them were more problem-solving, and one of them was walking through the data challenge

I applied through university. I interviewed at Capital One (Plano, TX)
Interview
1) CodeSignal proctored test. Tests analytical prowess and SQL. Time is tight, with increasingly difficult questions. You have to pass to move on.
2) Data Challenge. Python coding challenge to answer 5 questions. You need to merge/ clean your dataset and make a recommendation. You present it during power day.
3) Powerday. 4 interviews back to back. 2 case interviews, 1 behavioral interview, 1 data challenge interview.
Powerday 4 rounds back to back. One data challenge presentation , two cases and one behavior round. Overall easy and it was a nice experience. Interviewers responded the follow up questions detailedly.
