I applied through college or university. The process took 4 weeks. I interviewed at Capital One in Oct 2016
Interview
Submitted my resume though on campus recruiting. Selected for an interview, which I did not know at the time but was entirely case based, no behavioral. The case was very straightforward and just had a ton of math. I somehow made it through to final round and turned it down because I had another offer somewhere I wanted more.
I applied through an employee referral. I interviewed at Capital One (McLean, VA)
Interview
Multiple rounds of interviews spanning the course of a month culminating in a "power day", a full day interview series in one day, requiring preparations and testing. It did not end in an offer but the sheer breadth and time commitment seems designed to turn away candidates.
Interview questions [1]
Question 1
In the quantitative portion, they will give you data sets asking simple calculation questions.
After the initial application I spoke with a recruiter who scheduled a virtual interview with 2 hiring managers both sessions being 30 minutes each back to back. After those interviews I waited about 3 days or so to hear back with their decision.
