Knowledge of the actual product or company is acquired through in-house training.
However, a retail field representative will often have a degree in marketing or business, human resources or communications. They need to be familiar with employee training, as well as the best way to promote and sell a product.

In addition, real estate field representatives need real estate and business-related degrees to assess potential sale price and investment issues.
