I got a call 2 days for an interview after applying and was told to come in anytime that day. I arrived no later than 1 hour after getting the phone call. I was brought into the middle of the kitchen and we stood for the interview. The manager told me right off the bat that she doesn't like me because of my colored hair (already planning to change for job) and she told me to come back the next day because she had things to do and didn't want to waste our time.

Pretty simple, asked about school and work experience. Will ask about time availability and ask you about your strengths. Was not very difficult and was fairly short for a typical interview.
