I applied online. The process took 2 months. I interviewed at Capital One (McLean, VA) in Oct 2022
Interview
First an online assessment through Codesignal. Give yourself enough time to prepare, and I would suggest doing the challenges and practice exams on Codesignal. After the assessment you schedule your Power Day. 4 interviews with a 30 minute break after the first 2. Again, give yourself time to prepare and get a further date if you need to. For the coding interview make sure to explain your approach to the interviewer before writing any code, and as you write the code to make sure you are both on the same page. After you solve it, be able to explain the time and space complexity of your solution. Also practice system design and have some stories that capture your strengths for the behavioral interview. The case interview was more technical than the example case the recruiter provides and will require walking through code with the interviewer, but the concepts of communication still apply. Overall process took about 2 months for me because I spread out OA and Power Day, and additional team matching interviews if you pass.
Interview questions [3]
Question 1
Coding question might involve working with numbers in a list
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
