Any tips for an interview for an HR position?

I’ve got an interview tomorrow with my current company for an HR position. I haven’t interviewed for anything in over 3 years so I’m pretty rusty. I’m not sure what to ask. I work in grocery retail and this HR position is not directly in charge of hiring or interviewing. Does anyone have any helpful ideas or tips for my interview tomorrow?
