Explain how your experience as a server helped you improve your drink knowledge. For example, taking the initiative to learn about the drink menu helped give you the confidence to upsell and increase your beverage sales.

"Before becoming a barback, I worked as a server assistant and as a server. My beverage knowledge was limited when I became a server, and I had difficulty getting drink orders correct. Before my shift and the dinner rush, I asked the bartenders questions and watched them prepare drinks. Eventually, my knowledge improved and I transitioned to becoming a barback to increase my beverage knowledge."
