got an interview at a schoool!!

So i got a calll and i got an interview at a school on tuesday for Transportation Attendant for special ed students. Im so nervous because i never been that before. I was wondering what kind of interview questions will they ask me ? just about the position questions? i know interviews take like 5-10 mins.. my last took like 5 minutes. I don't even know what to wear lol 😩 i hate interviews i tend to freeze and get nervous and stutter. and then i won't get the job after that...sadly
