Second, ask questions in the words of experts. An expert will know if there is one if he reaches out.
Third, ask some simple questions to calm the mood of the interviewee. For some interviewees who can't get into the state quickly because of excitement or nervousness, in order to calm them down, we can talk about a relaxed topic that has nothing to do with the theme first. Let the other person relax through relaxed topics and shorten the psychological distance between them as soon as possible. A potted flower, an experience, an opinion on a problem, or the other person's hobby can all be the topic of asking questions.
