Capital One Senoir Software Engineer interview questions

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.

I had a very good experience in the process. The interview questions were good but I didn't optimize the code well. The other technical interview was a kind of uncommon, it was about the cost of regression test interms of budget. I have never thought of this scenario when I was preparing for the interview.
