On a daily basis I worked with customers to show new products and take reorders of current placements. This was an outside sales position so I was responsible for my own schedule and meeting all sales quota numbers.
The hardest part of the job was probably dealing with problems that were out of my control such as delivery mistakes, out of stock items, etc.
The most enjoyable part of the job was dealing with my customers on a weekly basis for multiple years. During that time I met with these people on a weekly basis and several strong professional bonds were created.
The relationship with my co-workers was a good one. Most of the interaction with co-workers was with office staff to whom you placed orders and coordinated deliveries.
