What motivates you? Even though good motivation is key in any career, your interviewers will want to know how passionate you are about selling a product or closing a deal. While answers will of course vary from person to person, you should convey enthusiasm for the sales/marketing career path and a desire for the product to succeed. Discuss your personal style within sales/marketing and comment on how this drives your work. Share an example of a time when you saw an opportunity and went the extra mile to sell or market something exceptionally.
