I applied online. The process took 2 days. I interviewed at Capital One (Chicago, IL) in Jun 2015
Interview
Very quick as it was an internal job posting that I applied to. I got a call from the recruiter and then the hiring manager invited me for an in-person round on the phone. I then had a case interview.
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.
