How many interviews should I have for the undergraduate thesis interview? According to Zhihu's information, there are about five interview methods, and the specific number needs to be considered as follows:

1. Research purpose and questions: The number of interviews should be adapted to the research purpose and the complexity of the questions. If the research purpose and questions are simple, the number of interviews can be reduced appropriately; If the research objectives and problems are complex, the number of interviews can be appropriately increased.

2. Characteristics of interviewees: The number of interviewees should consider their representativeness and diversity. If the interviewees are representative, the number of interviews can be appropriately reduced; If the interviewees are not representative or need to consider diversity, the number of interviews can be appropriately increased.

3. Time and budget: The number of interviews should also take into account the time and budget constraints. If time and budget are limited, the number of interviews needs to be properly controlled; If time and budget are sufficient, you can increase the number of interviews appropriately.
