1. Draw up an interview outline, including: collecting interview materials, determining interview time, interview content, interview focus, interview process control (opening, text, transition, episode, ending), interview ending, host's speech, and making plans for possible emergencies during the other party's conversation.

2. Contact the interviewee before the interview. Mainly through timely communication with the interviewee, we can understand the interviewee and reach a tacit understanding with the interviewee in interview content, interview theme, effect control, interview coordination and so on. In particular, it is necessary to dig deep into the important information of respondents in key content.

3. Link to the background information of the talk show or the theme background information (such as "The disclosure of the dormitory janitor uncle and his views on the current situation of contemporary college students" mentioned in your topic), mainly to collect and shoot some background shots, such as scene reproduction, related scenes, speeches of characters, etc.

4. After the above preparations are completed, send the prepared interview outline or script to the department head for review, modification and confirmation. Next, you can do some warm-up activities and rehearse with the interviewer. On the basis of the above, you can take a bold gamble.

It is very important to do a good talk show, just like CCTV's talk show. We should tell the audience some real situations and their inspiration vividly and credibly through interviews with people. Whether the preparation is rigorous, thorough and comprehensive is the key to the success of the interview.
