Store associates work in retail businesses assisting customers in making their purchases. They help you find the right size or color of whatever you are looking for and tell you it fits perfectly, or that they have the same kind at home. And this still works like a charm after years of regular use.
They know the answers to all your questions, as far as the products of the store are concerned anyway. They manage stock, reorder shelves, and arrange the displays in shop windows.
This is an entry-level position where a high school diploma is more than enough to get hired. You just have to be friendly and patient, promptly at the service of customers to provide support and resolve any request or complaint.
