Capital One Software Engineer interview questions

Round1: Phone interview with a recruiter/HR. Round2: An online, automated, assessment via Hacker Rank. Round3: A three hour interview with three different people, back to back via Zoom. No break. Round4: An interview with a manager via Zoom. It was awful. I withdrew my application. For round 3 they send an email saying your interview could be any time between 9:00AM and 5:00pm. They send you another email the day before the interview of what exact time it is. Who thought 3 hours of back to back interviews was a good idea? I didn't get a break. The fourth interview was supposed to happen the same day round 3 but the interviewer rescheduled and I wasn't notified.

The whole process was around 45 minutes long. It was pretty clear and brief. The interviewer was friendly and helpful throughout the whole situation. They asked me a couple of questions about my past internship experience and side projects I have done.
