A demonstrator is a person that shows potential customers how a product works in a showroom or other commercial space. As a demonstrator, your duties revolve around giving a presentation to an audience and showing them how the features of a given product can help them. The goal of the demonstration is to teach customers how to use the products and get them interested in eventually making a purchase. In some positions, you may get paid on commission, so sales experience and skills are crucial. This career requires travel to various locations, including retail stores that sell the product, in order to give these demonstrations.
