Interviews can take a variety of different formats, with children interviewing or being interviewed.
The whole class may take part, or the interviews could be conducted in small groups. Interviewing the Teacher - The children could interview their teacher about his or her job, and why they like being a teacher. Interviewing the Class - The teacher could interview children in his or her class. Interviewing other Children - Children from other classes in the school could be interviewed. This would give your class an understanding of what younger and older children are interested in, and how they feel about school etc.
