Never had a problem with a kitchen member? That's great news! Tell the interviewer that you have never had a bad experience with a member of the kitchen and have been very fortunate to always have wonderful co-workers!
If you have had a bad experience with a kitchen member, it is acceptable to share it. The interviewer will be most interested in how you responded to the situation. Start off by giving the interviewer a high-level overview of the situation. You might say, "I had received 3 complaints in one night from customers that their steak was not done the way it was ordered." Next, share what you did to resolve the problem. You might say, "I doubled checked that I had written the orders down correctly, and when I realized they were written correctly, I pulled the kitchen member aside and told them what had been happening. I mentioned that I had three customers complain about their steak not being done to order. The kitchen member felt really bad and appreciated that I brought it to their attention. That was all it took! I never had another complaint like that again!" Being sure to mention the positive outcome of the situation is always a nice way to end.
