If you are an interviewer, how do you judge whether people are what you need most?

Law of attraction. If the interviewer sees that you are the person you want, it is basically 80% successful. To tell the truth, the first impression is less than three minutes. A well-trained Hr must have read your resume carefully before deciding to let you come for an interview. I have a preliminary understanding of you. The rest is image, temperament, and speech. Don't worry, the interviewer won't ask for anything noble and gentlemanly for a junior position.
