Pros

Company pays little higher than market for consultants in IT

Cons

this is a endless list for ppl working in IT Fulltime staff doesnt get rated their salary properly so its flat structure with similar salary range for everyone, good for someone who doesnt have good credentials IT executive management is a joke Nothing to learn in the organization whether its new technology or process management More managers than developers, all technical managers are dummies.

Strong teams, large organization with a lot of resources, good benefits and earnings opportunity for high performers. Growth opportunity, strong name recognition.

Cons

Centralized control. Large national customers "wag" the dog. Highly political corporate management structure. Favoritism is often the deciding factor in promotions.

Pros

Cafeteria food is decent and the building is nice

Cons

This place has really gone in the gutter over the years, hard to see how it will turn around. If you’re thinking about joining, the industry is Good but I’d stay far far away from GAF
