Pros
Lots of equipment to learn. I have never worked in a place that has so much equipment on the floor until Shutterfly. There isn't a boring minute. Especially during peak season, you will be engaged from start to finish with servers crashing, printer malfunctions, desktop rebuilds, relocations of Machines, Installation of Software and troubleshooting.
Cons
Unity is lacking in so many areas. Team Spirit is weak. At times, I felt like I was on trial. There is a constant oversight looking for failures. You have to deal with (shadow managers), those wanting to be managers in your department, especially with those Administrators who have tenure over you. There is continuous backbiting with the attention of tearing down and tarnishing others versus lifting each other. A lot of this is hidden and even managers don't see it. This is corporate America. You will be tested. Develop thick skin and do everything by the written procedures and you will be just fine. (I have high regard for the IT Manager, he tries to promote teamwork. You will not find a better person. )
