This is not a career that anything is handed to you. Part of the belief with Enterprise is that "We work hard, and we reward hard work". This is true!
It is very long hours BUT if you are good at sales and have a teachable attitude you will be promoted. As well, the nature of who Enterprise hires with its MT Program are recent grads. Everyone is basically the same age and have similar interests. The company provides monthly paid outings to reward staff for their hard work and commitment. Also, because of the MT Program and promoting all from within - whatever stage I was at, I had supportive Managers that had been in my shoes at one point and understood my struggles, coached me and helped me to move forward.
I learned a lot about sales & customer service, Human Resources in a Coordinator position I had been promoted to, and loved working in the team environment.
The reason I gave it a 3/5 is that it is a great place to start a career - but it is not for everyone. It may feel in the beginning that you are giving your life to Enterprise - but on the flip side it is one big family. You will meet life long friends that are supportive of you and your career advancements.
