Pros
Great pay for experience and allows you to break into the industry. Many avenues to transfer internally.
Cons
Politics everywhere. I was an employee at three different physical locations, all filled with disgruntled employees who wouldn't do their jobs. Several other employees and I would be burdened with all the burden, but I would get to work. IT, in particular, is rife with people who do nothing. Management will lie through their teeth if it means they can keep stringing you along to work harder without compensation. They have an impact award, designed for going above and beyond, but it is often used instead of paying employees for overtime pay. This would be fine except you generally get paid significantly less than what your salary would be. When placing boundaries with management after an internal Shakespeare's of I need to be notified at least a week before coming in for an entire weekend, I got met with hostility. Then, a made-up scenario that sent me to HR was disingenuous and portrayed me as flying off the handle and losing my temper when the manager was screaming at me for asking a simple question: Are we upgrading these computers to a particular OS? There are way too many managers telling everyone what to do constantly, you could do with 1/4 the amount of managers and twice the workers.
