Pros
Great place to get experience in sales and customer service. You'll have plenty of time during the day to learn sales skills over the phone, since that is the majority of the day. You'll also have the ability to drive all different vehicles all of the time. The office environment is great! You'll never have a dull moment throughout the day. Overall since you are out and about and multitasking to the fifth degree your days hardly every drag.
Cons
The biggest downside to starting out at Enterprise is that you will have four to five people telling you what to do. At my office there is my branch manager, my assistant manager, and two management assistants that all delegate stuff right down to me. The other part is not completing something crucial to the daily operations because you have to stop everything and drive a customer home or pick them up. I have cause a few headaches for my branch manager because cars return and you know they have but you can't pend any contracts because you have to have a sense of urgency and hop to any customer's wants and needs. Thats where the ESQI comes into play.
