Vantaggi
International company with many different cultures, great people. The company over all seems to care about their employees, the head of HR is an amazing kind heart person. That being said Fluor is a large company and I can only speak for what I've seen being at the corporate office.
Svantaggi
Politics run the show... to the point that job your boss wants you to have, could be over run by someone else's suggestion because the suggestion comes from someone more senior than your boss who suddenly knows the department better than your current boss does... I have seen many professional friends lose positions they were promised due to "suggestions" from higher ups. Fluor is a good company to work for, it's just sad to see politics get the best of people sometimes.
