Pros
If you don't have a life, and you really don't want one, then this is the place for you. The upper management doesn't have a clue.
Cons
The upper management doesn't have a clue in this company. One month they are downsizing from 4 to 2 datacenters. After 18 months of migration projects to get all the servers, proper training, beef up the infrastructure, and hire more staff, then they decide that this was a bad idea and start re-hiring for the positions that they just laid off....but they won't hire any of the people they laid off. After all this crap, years later, they decide that this whole datacenter consolidation thing was a good idea and consolidate one of the original 2 that they kept with another. This is after they spent a billion or so beefing up this datacenter with infrastructure and staff. They would spend millions of dollars on software packages that were never used and no one knew how to use. They worked you to the bone. Horrible....horrible place to work.
