Clark gets calls every week from people who want to become mystery shoppers. This is a coveted job that many people would like to have. But the truth is mystery shopping is a very selective business. There are some mystery shopping opportunities out there, but for the most part mystery shopping companies quietly seek out the candidates they want. According to the Detroit News, mystery shoppers who work in the car business are highly trained and usually have backgrounds in private investigation, bounty hunting or some research field. They evaluate how customers are greeted, how the business is run and, of course, they kick the tires on cars. They use codes when talking over the phone, and some even wear disguises and hidden cameras. It’s a very serious business that can provide very valuable information to consumers. More companies need to consider hiring mystery shoppers of their own to make sure their businesses are catering to customers.
