What performance of HR indicates that the interview failed?

First, the interviewer keeps making negative hints. When I interview others, if I feel inappropriate, I often express some negative news. For example, the overtime work of the post is very serious, and the required ability far exceeds that written in the recruitment, which makes the job seeker feel that it does not match the position.

Second, interview time is too short or too long. I have read many posts. If the interview time is less than 15min, it is often dangerous; In fact, this is not absolute. I have seen that the interview ended in less than 10 minutes, and finally I made an offer. It should be said that if the interview time exceeds the normal length of this round of interviews, it will be more dangerous.

Third, the interview is full of embarrassment: there is nothing to say about this, and often the parties themselves can feel that experienced and cultured interviewers usually wait politely for the candidates to finish.

Fourth, the interviewer is absent-minded: This situation is the most dangerous. For example, the interviewer is looking at his mobile phone, answering emails, chatting and joking with colleagues around him, or starting to be in a daze, which means that they are subconsciously finished.
