I'm going to the studio for an assistant interview. What questions will I ask in the interview?

Hey, hey, what a coincidence. I just went to the studio for an interview at noon, but I want to learn photography assistant. I asked a simple question there. The boss didn't say anything, just asked why you applied for this job. I said that I like photography very much, and I am interested in photography and want to learn. It's good to have a skill. Then he said that this business is very hard. Can I stick to it? I said I only wanted what I was interested in.
