I was asked 4-5 random questions that came to his mind. He wasn’t prepared for them, he was making them up right away with the justification that if he can’t answer his own question, and it would be an unfair question. All the questions had nothing to do with ability of thinking or knowledge and if you hadn’t ever faced them real time, then you wouldn’t answer.

I told him that the questions were biased cause you make them up based on your own experience and just ended the interview. Total waste of time.

The interviewer asked memory management style questions with nothing specific, but still wanted an answer without ever accepting anything as he didn’t have a complete scenario in his head.
