I applied through an employee referral. I interviewed at Capital One (McLean, VA)
Interview
First round is Mini-Case round followed by Power-day. Power-day has 3 rounds (2 cases and 1 product round). Might have to go through one additional round if they think it's needed.
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.
