I recently encountered an interview. The interviewer seems not quite willing to cooperate at the first beginning, like hiding the camera, not responding to my answers, and just shooting another question right after. Within 1-hour interview, the interviewer spend 40 minutes around behavior questions, most likely: "what's the most critism feedback you recently received?"/ "what's the biggest mistake you've done?"/ "give an example of when you think you received unfair criticism?". The interviewer also asked questions like "what's private cache/ global cache"? "What's the replacement for sharding?" still I do not have any clue about this sort of question. The rest of the tech interview, it's a dp question which I think it's quite challenging to accomplish in 20 minutes. I wonder what is this interview about. Is this kind of a high-pressure interview? Is this kind of interview that we should expect?
