Pros
Very good place to learn about enterprise computing. Vanguard's reputation in the industry is at the top.
Cons
When projects run over budget they'll cut you off.. without prior notice. 1/3 of all Vanguard employees are contractors. This is so they can tout the "We've never laid of an employee" line.. which anyone who know anything can read right through. Their contracts are written to be canceled without reason.. oh, yes the budget was reduced. Get your pay while you can. When the money is spent they'll let you go... or, just send an email to someone outside of VGI and they'll use it as a reason for dismissal if they want.. this is very common. Vanguard is all about getting value for their customers... even at the expense of the vendors. This is a very bad game to play, as you'll only hurt your suppliers and drive VGI's costs higher as they go bankrupt or up your costs. Obviously the best deal isn't always the best longterm plan.
