If you are currently a barback, why are you leaving your bar?

Focus on what the current company can offer you that your current employer can not. First, do your research and explain why you applied. Then, use your answer as an opportunity for you to show your excitement at the possibility of joining the team.

"The reason why I applied here is that my current employer is not going to expand. The owner is content with the one location and has expressed that he might sell in a couple of years. Many bartenders have been there for 3 years, and I don't see the growth potential for me. But, here I know you will open 5 locations in the next three years, and I want to be a part of that growth."
