Capital One Software Engineer interview questions

Very poor experience overall. I applied online with a referral, got the CodeSignal and completed it. Few weeks later, recruiter emailed to schedule final round interview. Now, I had told the recruiter multiple times that I had a pending offer by a deadline and to have the interview done by then. Recruiter ghosted me and then later said sorry, we have to reschedule for a new date. So I did, even when I asked for a bit earlier since the deadline is incoming. Very disorganized communication. As for the interview itself, first one was a case? interview which is very abnormal and not done anywhere else really. Second interview was behavioral, but the interviewer was literally reading off a paper and asked the most generic questions - it wasn't really even a conversation. Third interview was pretty hard technical interview question which I couldn't finish completely. They didn't even get back to me by my deadline, so I just accepted the other offer. C1 rejected me anyway a full week later, not that I was going to accept them anyway. I really hope you are not this unprofessional and disorganized in your day-to-day with your employees.

Applied directly on their site, and received a phone interview invite within a week or so. Phone interview was around 30 mins and covered overview of the company and asked some basic questions like 'Why do you want to work here'? Received an email with a link to the Code Signal. Took it a few days later and passed by solving 3/4 of the questions. Heard back within a day or two with results and schedule the onsite final interview. Onsite final interview had 4 rounds consisting of behavioral, case study, DS/Algo, and systems design. Heard back the next day with results.
