Do I need an interview before the college entrance examination if I want to go to the drama and literature department of Xiamen University? What is the content of the interview?

No need. Just take the college entrance examination directly. There are at least two points to note. The first point is that you have enough scores to reach the lowest score of Xiamen University in your province. The second point is that drama literature of Xiamen University should enroll students in your province. These two points are the conditions to ensure that you can study. I wish you success!
