Applied online, didn't get any reply. Heard from a friend who works there that I should apply online too, so I printed the pdf that I had been emailed that contained all my application answers. Handed it to the owner and got an interview for 3 days later. Basically asked me my age, what school activities I am involved in, what my employee friend might say IF he were to ask them about me, and went through what paperwork I needed to fill out and more of the details of my duties, since I made it clear that I did extensive research on the general information and duties beforehand. It was very casual and laid back, nothing worth keeping yourself up at night worrying about. Doesn't seem to have any interest in contacting my references, either. They seemed confident with what I had put on my application and the answers I had to the few, few questions I was asked during the interview process.

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.
