The answer to this question should be simple for you; however, the tough part is making sure you don't drag your answer on and on. Take just a minute or so to bring your resume to life for the interviewer. A simple overview of your role is excellent but be sure to add a few highlights or discuss and significant achievements.
"I have worked in the restaurant industry for the past eight years. I started as a busser and worked my way up into an assistant manager role a couple of years ago. My promotion came after I made some changes in scheduling and ordering which saved the restaurant a significant amount of money in workforce and excess supplies."
"I am newer to the restaurant industry; however, I do have some experience working in retail management. The experience that I can bring you includes inventory management, scheduling, staff management, merchandising, upselling, and more."
"I've been working in restaurants for ten years and have been in management for the last four years. I've performed in nearly every function imaginable. I started as a host, trained as a server next and then moved into a shift lead role. Management is my sweet spot as I am very organized and focused on budgeting."
