Pros
The people you work with are amazing. I wish I could take the majority of them with me to my new company. The position you are hired for (Management Trainee) is an entry-level position, so typically these are recent college graduates (like myself) with the same mindset and just learning how things function in a business setting. Area managers do make an effort to host fun events like happy hours, and after a while, you start setting up your own. The vast majority of people I am close to are people I worked with at Enterprise. There is a huge camraderie because you are sharing the same experiences, and Enterprise tends to hire fun loving, very friendly people, since it is a sales and service position. I also think they did a great job training me and getting me ready for the real world. I learned a lot about the business world and customer service while with Enterprise, and without that experience, I don't think I would have gotten my current position.
Cons
Well let's start with the obvious two: hours and pay. As an MT, you are not allowed to work more than 50 hours a week (management gets in hot water if you have more), but once you get into management, the expectation is 55-60 hours or more. As an MT, the pay is about average for an entry-level job, and benefits are pretty good. However, you are always under the assumption you will be paid more as a manager. I worked a lot harder as a manager, and my paychecks never lived up to my pay plan. So if you are considering working there, be prepared for that. That's not to say some people don't do well - some do. However, it is a highly male-dominated industry and company, so don't expect to see a lot of female managers. The ones that are up there worked their butts off to get up there though, and I have tremendous respect for them. It seems to be a lot harder to make it as a woman in the company than as a man. If you do come on or stay with the company, be prepared to stand up for yourself and fight for what you think you deserve - but be prepared to explain why as well.
