Capital One Sr. Software Engineer interview questions

I had an appointment with a recruiter for a phone screen but they never showed. Emailed to say I was no longer interested but the recruiter lied about having called and left me a voicemail which was false. I called them out on it and they didn't apologize but instead said they could reschedule with me if I wanted. Very unprofessional and a complete waste of time. They seemed unorganized from the start and I should have went with my gut and not moved on in the process.

First two rounds were good, but the third round ie hiring manager round was the worst. He was yawing and keep on getting on mute, which was quite irritating for a candidate. If you came to reject , don't take interview
