I seriously wish that companies would add this line to advertisements when they are looking for a promo person. Sure everyone loves to look at hot girls when their at the bar getting their beers. But there is nothing more annoying than a chick with a banging body with the intelligence of a peanut. (Sorry Mr. Peanut - no offense to you.)
Best example ever is my namesake Miss Jessica Simpson. Sure she is beautiful, but the moment she opens her mouth I just want to smack myself in the forehead. It's painful to even listen to.
After 4 years in this industry you'd think I would be used to the mental challenged handicaps I occasional have the misfortune of working with, but it still baffles me most days. How did they possibly make it through an interview?
Promotions are about getting a product out there to consumers (I know your shocked it's not all about eye candy.). If you can't form an intelligent sounding response to questions or even remember the products selling points then your dead in the water and you'll turn off consumers. I constantly hear similar comments from supervisors and team leads.
While being aesthetically appealing is definitely a key selling point in this business, it's having a personality that makes you stand apart and get the gigs.
