I applied through an employee referral. The process took 3 weeks. I interviewed at Capital One
Interview
Pretty quick process overall, I applied (with referral) and a recruiter emailed me 3 hours later. After a resume review call I did the codesignal tech screen which they give you two weeks to do, but the recruiter was pushing for me to get it done sooner. 4 questions in 70 minutes, the first two were a total joke not algorithmic at all, third one was much longer but not leetcode style, just some code organizing and processing i/o. Last one was a tougher LC medium at least, didn't get it but I still got 140 points for an easy brute force solution. You don't need to get a lot of points to pass, maybe 800/1200? I passed with 810/1200 because I ran out of time getting bogged down with the output formatting of question 3. Then Power Day was a week later, I was backend so it was case, backend system design, coding, and behavioral for the four rounds. Interviewers were generally pretty friendly.
Interview questions [4]
Question 1
Case Study : go over a Capital One feature and answer questions about how it works and why it works that way. Try to understand it from both a customer and engineer perspective. Second half of the interview round is then going over some data and basic functions and how you would improve the code. Coding portion of this very easy.
System Design : design a banking application. Probably interviewer dependent, my interviewer was grilling me on API specifics and it felt kind of tough, but I still passed.
Coding : like an easy LC easy, some string manipulation. However it then got interesting because I solved it quickly so my interviewer steadily built on the problem and asked probing questions about how we can make this harder and turn it into a real life question. Pretty good round and a lot of good back and forth from the interviewer.
There's a virtual onsite called the "power day". It was one of the better onsites I've had. The power day takes place fully remotely, and involves the typical kinds of challenges and interview questions you'd get from Square or Stripe.

Question 1
System design questions - how to architect a service
I applied in-person. The process took 2 weeks. I interviewed at Capital One (New York, NY) in Jan 2023
Interview
Meet with different teams throughout the day. Usually two people at a time but sometimes just one person. It was the typical "behavior" style questions, hypothetical questions and programming type questions using the language of your choice. Very little questions about me but there was always time to ask questions.
