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.
Power day style interview, two coding, one system design, one behavioral. Everyone was nice, but the interviewers seemed a little under prepared and/or new to interviewing in general. Questions where essentially leetcode medium/hard almost word for word.

Question 1
Leetcode Count primes, looking for optimal solution
Code assessment then to power day interview with 4 rounds. Overall the power day interviews were okay except for the case study. The interviewer was disengage while being on their phone the whole time. There was a part where the interviewer said fix the mistakes then went back to their phone. I pointed out their code has other errors with template and was ignored. Then while attempting to fix those (10 mins later) they mentioned to ignore that part and focus on the very bottom part of the code. What a waste of time and very unprofessional. This makes me wager a few of the interviewers probably could not pass their own interview process today.

Question 1
Code signal 4 questions. Power day is one coding question, system design, case study and behavioral.
I applied through other source. The process took 2 months. I interviewed at Capital One (Ciudad de Mexico) in May 2026

Excelente code challenge después de eso, preparaciones para un powerday q es básicamente 4 entrevistas técnicas en un solo día, es de 1 hora cada uno y al final de dicen si queda o no
