I applied online and within a week and a half I was called for an interview. The lady I spoke to was very friendly and welcoming, and simply asked when I'd be available and what I needed to bring. When I went I was asked to sit down and was given a drink of my choice. I was seen half an hour late, but apologised to for the delay. My interview as relaxed and asked a series of basic and personal questions and was very friendly. I was told when my application would be reviewed and when I'd hear back, and then was thanked for coming and for my time.

Very simple and straightforward. Normal questions like availability, have you worked in food service before, etc. I think it depends on location though since friends at other locations have had more substantive or less substantive interviews.
