Pros
There are great online resources through the Intranet for continuing education and you have the ability to easily find and contact colleagues around the world for collaboration and help. Compensation seems to be more than average and benefits are excellent. Like anywhere, there are good members of management and others who are not so great. Fluor has well thought-out processes and structures for the way they conduct business, so it's easy to learn a new job with a little dedication toward reading the available procedures and exploring the Intranet for information.
Cons
I think there are way too many layers of management and it seems certain people gain favor for promotion over others regardless of experience, contributions, and professionalism. The good ol' boy network and nepotism reign supreme. Be careful navigating the political waters. There are lots of family members working together and many apparently less than qualified members of management who hang on the coattails of those who are dedicated and truly interested in what is going on. Jobs can be very narrow in scope, and thus become monotonous and boring to a thinking individual.
