I applied through a staffing agency. The process took 2 weeks. I interviewed at Capital One (McLean, VA) in Oct 2012
Interview
Power day:They made me drive to McLean even though I was applying for a role in Richmond and they do Power Days there as well.
A few cases studies involving solving a business problem. The idea is to show how you can do the math as well as see why each iteration in the problem yields a contradictory answer.
Behavioral interview. "Tell me about a time where..." etc. If you know the SOAR method, you should be fine.
Interview questions [1]
Question 1
Some very specific job skill related questions such as: Do you know the difference between a left join, inner join, and outer join?
Recruiter Call, Mini Case and then a power day with 2 case studies and 1 product case study. Process was overall smooth. Appropriate documents and resources were provided to prep for the interview.
The interview was based on 3 phases. First was screening on call then a video interview with mini case then a power day with 3 phases including product interview, case based and economics based.
First, Screening call: the HR simply walked you thru the interview process and schedule the next round of interview - mini-case. I haven't done the mini case yet. Mini case, just search online for potential cases and prepare for it.
