Exactly what you would expect...Don't do it, you will want to switch back.
Pros
Large Company, dress code is not too strict. Many people are professional and the environment is very nice and updated in the headquarters. Many people are pleasant. Senior management professionals are very good at what they do.
Cons
Politics...way too much of it. Much like what Charter does for its customers, it does for its employees. They promise you the world, and then drop the ball on delivery. There are a tremendous amount of contractors and the place is kind of like a revolving door. It is very difficult to rely on any individuals for support, or as a resource as they may not be there the next week, very frustrating. On top of that, the mid level managers (who do stay) are always stuck on their stake or voice in any project and can't get past their own thoughts and opinions to see other people's point of view. This is not all of the managers, but defintiely quite a few of them.
