Got my first interview tomorrow, any advice?

I have no IT experience besides my A+ cert and a few homelab projects. I am in the process of going for the network + as well. I landed an Interview for a job that deals with printers and installing drivers on computers for them, as well as other maintenance and install work. Any advice on how to prepare for this interview? The job listing also doesn’t list the pay so any ideas on how to ask for that or answer that question if they ask me how much I am expecting? I live in Illinois for context.
