I applied through a recruiter. The process took 3 weeks. I interviewed at Capital One in Apr 2022
Interview
I was able to complete the application through a referral, and I was able to hear back about the first round after a few days. From there, I was assigned to complete their coding assignment on Codesignal, which I had about a week to do. There were four questions, two easy and two hard/medium.
I heard back after completing the assignments after another few days, and was introduced to their "power day" of interviews, which took place over the course of several hours. It consisted of a standard behavioral interview, a case interview, and another technical interview. The behavioral interviewer was engaging and informative, and there weren't any unfair questions. The case interview was also engaging, and seemed more designed to see how you solve and approach problems. The technical interview was an easy LC question followed by a hard LC question, and was straight to the point. The interviewer was also knowledgeable and made light suggestions when necessary instead of being completely silent/ too oppressive. All of these are described in detail by the company beforehand, so you have plenty of opportunity to prepare.
Interview questions [1]
Question 1
The behavioral portion was very standard, just be familiar with work you've done in the past and be able to describe the problem and how you solved it.
The technical portion was a LC easy/med followed by a LC hard. The questions for the company on LC are a good guide.
One power day with three rounds (technical, behavioral, case). Technical was a OOP design problem and the case study was pretty similar to the practice video they share. The behavioral was standard.

I applied through an employee referral. The process took 3 weeks. I interviewed at Capital One (Richmond, VA) in Nov 2025
Interview
just like others have described, it's a 4 hour interview (1 hour case study, technical, break, behaviorial). Behaviorial is pretty standard, technical and case study honestly aren't that bad and definitely studyable. However, it's still pretty difficult and definitely study up. It's not like a leetcode.
