I applied through a recruiter. I interviewed at Capital One
Interview
HR phone screen (30min) - 2weeks later, mini case (1h) - 1 month later, power day (3 business cases + 1 product interview) - 1.5m-2m later, team match. Long process
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.
