I applied through an employee referral. The process took 1 day. I interviewed at Capital One (Chicago, IL) in Feb 2016
Interview
After a screening/informational phone interview with the Capital One recruiting contact, the contact sent materials to prepare for the interview, including example case and behavioral questions. The interview day included two 45-minute case interviews, a behavioral interview, and a less formal lunch and tour. Interview results followed about a week later.
Interview questions [1]
Question 1
The interview cases and behavioral questions were very consistent with the materials from the Capital One website and the documents & links the Capital One recruiting contact sent. The cases' subject matter is relatively straightforward, especially if you are familiar with profit/loss/break-even analyses and setting up & solving algebraic expressions. Despite this fairness and relative predictability, passing the cases is challenging.
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.
