There is a power imbalance between interviewer and interviewee. If an interviewer really wants to, they can throw you the equivalent of "what number am I thinking of" and watch you struggle through 50 tries before your brain runs out of glucose and you go blank. If I'm interviewing someone and they give me a right answer that wasn't even in my copy of "the teacher's answer book", I realise they're good and let them ace it. It maybe be that there was a personality clash and they simply didn't think the candidate was a good fit for the team. Been there, and understand that. Or they maybe got butt-hurt that the candidate's answer broke their test. Either way, the candidate is better off not working there.
