The process took 1 day. I interviewed at Capital One (Arlington, VA) in Oct 2011
Interview
Initial communication and interaction with the company highly positive- they arranged several open bar/hors d'oeuvres mixers (one following campus career fair, the next for those accepted for first-round interviews). Pride themselves on unique, internal strategic focus. Culture is much more similar to consulting than banking. Interview consisted of "getting to know you" questions, which were largely a formality, followed by a case interview. The case interview is slightly more quantitative than the majority of consulting interviews, but still follows basic case style. Keep your thoughts organized, know what each number refers to (and decide if some of the information you've been given is irrelevant to the specific aspect of the question you're trying to answer then before incorporating it in your answer), don't hesitate to ask questions, think before you speak, all of the standard advice.
Interview questions [1]
Question 1
Market sizing and cost-benefit analysis of advertising channels: facebook vs. email.
Initial online assessment comprising of business case questions with a lot of red herrings, followed by a mini case and buddy call. Mini case was on profitability and interviewer led.
3 rounds of casing interviews. Very math heavy and quantitative. Cases got more complicated with each level and longer than average interviews. 1 hour for each. Very little behavioural focus

Interview
First, I completed a one way interview conducted through HireVue, where I recorded responses to preset questions, and then I proceeded to an actual interview with a recruiter, which allowed for a more interactive conversation about my experience, skills, and overall fit for the role.
