First of all, to fully understand the interviewees, we need to collect enough information, including all social software and social platforms; In addition, in the process of collecting information, we should collect it with questions in order to dig out valuable information.
Secondly, summarize the interview questions. You don't need too many interview questions. Choose what you think is the most important and interesting, and of course, choose a few more as alternatives. Another thing to note is that you must never involve the privacy of the other party.
After the first two preparations are completed, an interview invitation will be issued. Send an invitation 2 to 5 days in advance as far as possible, so that the interviewee can arrange the time and then determine the time and place.
