It is so typical to interview very senior people who get really arrogant about their skills, but when it comes down to it, they fail at this rapidfire, and in a very non graceful way. This rapidfire is very coarse and weeds out most incompetent people. It's likely not your answers, but your attitude that failed you.

Unlikely, unless the interviewer was just trolling them.

If it was just their attitude, they’d not tell them they were wrong when they weren’t and tell them to work on x y and z to be qualified in the future. They’d just complete or end the interview and say something like, “Great! You should hear back in x days” and then reject in their ATS.

If not, then the recruiter is an asshole and gaslighting the candidate.
