Preparing for an interview in a Catholic high school library

Hi everyone! I've been invited to an interview for a Library Technician role at a private Catholic high school (Melbourne, Australia). It's been over 5 years since I last worked in a library (currently work at a library vendor), and 6.5 years since I worked in a school libraries.

I'm trying to think of potential questions I may be asked, as well as questions I would like to ask. I tried searching through the subreddit but couldn't find anything that suited the role I am applying for.

If anyone has any suggestions/ideas on what I may be asked, and what might be worth asking, please let me know! I am both very excited and very nervous. I'm also unsure if/when I mention that I may need to take time off here and there for medical appointments (I won't divulge the diagnosis at this stage).

Thanks!
