Capital One Senoir Software Engineer interview questions

I got hit up by a very friendly recruiter initially. He quit in the meantime. I did the code signal, and it was two leetcode easies and two mediums. They grant partial credit. If you come up with partial solutions to mediums they will move you forward to the power day. Questions are leetcode adjacent but not on there. Power day is the super day in normal parlance. Four stages. First is banking app leetcode question sort of but they up it by keep asking you to improve it. At the end of that interview they asked me for top k users which is a doable medium question but not if you have 10 minutes to do it. Beforehand it’s something like put a user in a hashmap and subtract or add a digit. Next is system design. Like everyone says it is a very basic ask to create a credit application. Don’t expect any questions about stuff like sharding. Basic API outline is okay. Next interview is either behavioural or case. Behavioural follows STAR format, so just describe how you saved the company from an invasion by North Korea. I had to do the Business case last. The interviewer is gonna read out a very basic simple case to you. It will be simple but you can’t take notes, and it’s hard to follow a hypothetical business scenario so pay attention! It’s a company secret. They will actually say that about the console app they show you. He or she will then show you a program with 250 lines of code with a minus in the wrong place. It will be up to you to restore the balance at Capital One. After jumping through the hoops they called me three day after to say the jumps were not great. I thought they were but the beauty is in the eye of the beholder. At least I wont get pipped this year. Kidding aside, everyone was genuinely friendly and really tried to help me along during the Interview. So all the best to everyone! Oh and the recruiter will call to tell you the result. Even if you don’t get it because that’s the efficient thing to do.
