Cartier S.A. products are in the multi-thousand dollar price tag arena. Assure the interviewer that you are able, and comfortable, in selling products with a more significant price tag. Use examples from your work history and talk about a massive sale or large sales target from the past.
"I started my career in luxury sales with company ABC and, after spending two years there, I moved on to company XYZ which was an even higher price tag. With ABC, my average sale was $2500, and with XYZ, it was $6500. I am accustomed to sales quotas of $1M plus and would have no issue asking for the sale when it comes to a $10,000 luxury handbag or fine couture item."
"I have a total of 5 years' experience in luxury sales. This experience has included designer labels, diamonds, and cars. I am most comfortable working in a luxury setting and would fit in very well here at Cartier S.A.."
