Capital One Sr Software Engineer interview questions

Needlessly long process. Involved a prescreen, a coding challenge, a technical interview, and a "power day". The power day is a series of 4 1-hour long interviews over the course of a day: one code based technical, one "case study", one behavioral, and one systems design technical. The first three interviews went well. The "case study" felt out of place and weird, it was kind of technical but with more of an emphasis on business logic. There isn't a great way to describe it, and if you try to look anything up about it beforehand, good luck. The last interview went poorly. The interviewer joined 5 minutes late, ate up 10+ minutes with their introduction, had an accent that was difficult to understand, and generally seemed a bit arrogant, The question was way too involved to reasonably answer within the remaining 40 minutes, and the interviewer kept interrupting in a non-constructive way. It felt more like nit-picking. Of course I'm not going to be able to go in-depth when I have a 5-part question to try to answer within a 40 minute period. It felt like everything I said was being overly scrutinized, even when I was just thinking out loud. In the end, I was barely able to finish the first part of the question. And then the interviewer goes overtime afterwards bragging about how great it is working at Capital One and how good their 401k plan is. Felt completely unprofessional. At least now I know why he showed up 5 minutes late to the meeting.

Entire process takes 2-4 weeks 1. Get an email to schedule a call with the recruiter 2. Speak with recruiter to talk about the position and yourself, then they'll send you a coding assessment on CodeSignal 3. Take the CodeSignal assessment and schedule a call with recruiter 4. They'll let you know if you passed and then schedule a Power Day if so 5. Recruiter will email you asking to talk on the phone and give you some feedback. If you passed the Power Day they'll schedule a call with a hiring manager (they usually have multiple teams with the same role) 6. Speak with hiring manager and then your recruiter will call you after. If everything went well with the hiring manager, then they'll talk with HR for an offer 7. Get an offer Overall, I think the interview process is a great experience and yes you'll be exhausted after your power day. Make sure to pick a language you can use efficiently, because you need to be fast (1 hour per interview). Also, make sure to practice system design, obviously use AWS services in your design since that's what they use.
