Pros
It truly is a crash course in business management. You learn every single aspect of running a business in a very short time. You pick up skills in accounting, logistics, customer service, training, the list could go on forever. I always had great managers that were very flexible and had not forgotten how it was to be the "grunt". Coming out of college you work with people your age which is so much fun, there is a lot of independence and you are constantly in and out of the office and talking to all walks of life. You start building a great local network and connections especially with auto dealers so cheap oil changes! It was very fun because the people made it fun; otherwise we would have probably burned down the office. If you have no family, or don't care about your family and can sell anything without remorse and do not mind slaving away this job could be very rewarding and lucrative if you can stick out the first 5 years.
Cons
50 hour work weeks are the norm as a trainee and it gets worse in upper management. Do not expect much time off, they do warn you about this. Depending on your branch management you tend to become bill collector and repo manager because of the clientel that wants rental cars. You could have the best management potential in the business but if you cannot sell damage waiver you cannot promote. You must be very sales oriented and not mind selling something you may not agree with. You get to wash cars in the rain, sleet, snow, heat, all the while in your nice business suit (again you are warned about this) It is still very much a boy's club in some groups. The pay absolutely sucks; especially since senior management is looking at 100-400k while everyone else is struggling to put food on the table. Also prepared to be b*!ched at by 80% of customers who for some reason believe you are the reason their car is wrecked/broke/POS and the rental car you put them in well never be good enough. Also you will be filled with anxiety every time you walk a customer to a car because you are not sure if it will reek of marajuna or cigarettes or be absolutely filthy inside unless you are at one of the few blessed offices or an airport. Your life will center around Enterprise because it sucks every bit of time and energy from you. There is NO and I mean ABSOLUTELY NO WORK/LIFE balance even with "flex time" you will eat sleep breathe ERAC.
