Why do you want to work in retail?

"I want to work in retail because there is an opportunity for growth and advancement, there is competitive and rewarding compensation, and I would love the opportunity to interact with customers regularly and provide exceptional customer service" is a good answer to this interview question.

Retail is a fast-paced and dynamic field, and this is an exciting prospect for many that want to work in the industry, so you might try to inject this angle into your answer as well. Touching on the rewarding compensation and commission-based bonuses is also a good way to show potential employers that you are motivated and plan to work hard.
