Prince Music interview questions

I was called a few hours after apply. It was a short phone interview with HR. They asked me about my experience teaching and I have direct experience with this position. They said they would not be able to make this a full time position because then I would have too many students(?) (which I have had over 300 students schoolwide before so I don't understand that). The interview started to lean towards my retail experience and HR was interested in me working in their retail store as well, though they did not have an available position at that time(?). They asked how much money I was making at my most recent roles which is not appropriate for many reasons. The role sounded similar to something I had had before where I did not enjoy the schedule so I expressed that I was no longer interested.
