It is important to have knowledgeable sales people. Since they are the front line between the customers and the organization, you want them to be armed with product knowledge. In today's information-rich society, there are many ways for a person to gain that knowledge. As a potential employee, make sure that you understand how to get the information that you need. Do not be afraid to ask if there are seminars, or informational materials that have been written about the products that you might potentially sell. Customers trust knowledgeable salespeople who are not aggressive and pushy.
