Gen Korean BBQ interview questions

Basic interview questions. Tell me a little about yourself. How did you deal with an upset costumer? When did you face a difficult challenge and how did you overcome the challenge?

Very quick 5 min interview where they go over your resume and ask about experience. Since I had previous restaurant experience I was hired on the spot. However, I applied for a server position and they told me I would need to be a food runner for a few weeks before I could move up.
