I applied through an employee referral. The process took 3 weeks. I interviewed at Capital One in Apr 2023
Interview
3 step process as mentioned in other places here: 1. Initial screen with a recruiter who interfaces with you on behalf of Capital One 2. CodeSignal technical assessment. 70 minutes with 4 questions. Definitely a better strategy to go 1,2,4,3 since the 3 question is a longer one. I scored 710/1200 I believe and still passed 3. POWER DAY. 4 50 minute sessions, one behavioral, one case study, one software design, and one coding. They provide documents going over each of them and have youtube videos outlining them that I thought were nice. My software design interview was nothing I've experienced before since it was designing for 5 features in 45 minutes...
Interview questions [1]
Question 1
Basic behavioral: time you learned something new, time you had a disagreement, time you experienced a shift in priorities on a project Case study: A capital one feature, exploring the benefits and drawbacks, and then interacting with some basic code. Coding exercise: I wish I had practiced this more with others. I had to revise my criteria 5 times before understanding the desired input. Next time, I should be more comfortable with silence and working the input to understand the ask. In the end, my code ran but with one embedded for-loop. I was asked to clean that up even though the embedded for-loop could only contain a size of 3...honestly, my bad for not having a better response Software Design: Design a MVP for the following features: 1. cc application 2. posting transactions 3. Viewing transactions 4. Viewing daily, weekly, and monthly stats 5. A last feature that I didn't get to... I have no idea how I'm supposed to design an architecture with each of these features in mind and optimized in 45 minutes...
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
