Pros
The co-workers within whatever team you are working on, that are on or around your same pay-grade, tend to be very nice to work with. If you like politics and have an interest in Information Technology, than UPMC might be for you. You get a paycheck every two weeks and benefits are reasonable.
Cons
Nepotism throughout the organization. There is a lot of people who really shouldn't be in the positions they are in. Some IT vendors are chosen not for the quality of their product, but who in executive management has financial interest in or otherwise is getting a kickback of some sort from. Many in IT Management don't have any technical background which leads to a lot of wasted time and money since decisions will be made on IT management's misunderstanding of problems, leading to solutions to problems that don't work. IT management typically will find a scapegoat below them to blame for their uneducated decision. This tends to be the low to mid-paygrade folks(non-management).
