This question is a standard interview question for any position, but it's essential not just to read them your resume. The interviewers already have a copy! Be sure to talk about your sales experience, highlighting your most significant accomplishments. This task is especially important if your resume doesn't give a full picture of how much sales were involved in a seemingly non-sales position (think: hospitality industry, customer service, account management). Show off! Explicitly state your transferable skills.
"I have been in sales for a couple of years now, primarily as a business development team member. I will spend most of my day cold calling, up to 50 calls per day. The main goal is to fill my appointments with new customers. Currently, I am the top rep in my office, earning a close rate of 67% with a company expectation of 25%. I know I am ready to take the next leap in sales and add some account management, and outside sales experience, to my roster of experience."
"I have been selling since I was a little kid. I used to make my brothers work the lemonade stand with me, to their dismay. I set records for most Girl Scout cookies sold, and same goes for a fundraiser for my high school soccer team. I've been at the same restaurant job, but moved up the ranks, since high school and all throughout college. I worked the host stand, then carry-out, then as a server, and now also I do stints as the counter/bar person as well as shift lead. I have consistently set records for sales contests to the tune of management setting special rules for me after I won the monthly contests six months in a row. What I lack in traditional sales experience, I make up for in hustle and years spent figuring out how to sell to and deliver impeccable customer service."
