A brand ambassador-promotional model is someone who works in marketing or advertising and is an expert on a certain product or product line. In this role, you spend a lot of your time demonstrating the products you are marketing to show consumers how the products can work for them. You often work at trade shows, stores, or even bars and restaurants. Expect to spend time traveling, whether locally or nationally to promote the brand. This career is full of everyday human interaction and can also involve working with the media. The ultimate goal of a brand ambassador-promotional model is to turn a previously unknown or moderately known brand into a household name.
