Avantages
CSC has interesting opportunities for lateral movement, and in some cases, advancement, but you have to be very diligent in searching these out and spending a lot of time pursuing them. CSC is very "good old boy" network in approach, and if you don't know people, or don't play the political game, it won't matter how good you are, you'll get passed over. This is a plus if you're willing to spend a lot of time trying to get at these opportunities, especially on your own time since work hours seldom allows you the leisure to do this.
Inconvénients
Senior Leadership focuses solely on budget issues and they're always in emergency mode, trying to find money even after whittling down the budgets to their minimum. You can be dealing with an outage or other emergency and they'll still expect you to dial into hour long calls trying to find money that senior management wants found. Client satisfaction falls by the wayside while this is going on, and then they'll wonder why accounts are lost and client satisfaction is low. At this point the blame will be on you for not being able to be in 4 different places at once. Travel & Training are the first things to go in the budget, so forget about being trained. Downsizing is a periodic event, as there's no other place left to find budget dollars. This turns into a vicious circle as performance falls each time the exercise is run.
