Pros
Lots of different types of work available. Lots of friendly, intelligent people to work with. Decent benefits. Flexible schedule and ability to work from home (if the Arcadis IT -- VPN, Citrix, etc -- isn't completely useless at the time).
Cons
Terrible communication between operations staff and upper management. Pockets of expertise littered across the country with no way to find or utilize that expertise. Miserable (terrible performance, stability, accountability) IT infrastructure. Large wins are credited to project managers with no acknowledgement of the staff that actually completed the work. Company makes a show of listening to the opinions of all employees but very little evidence that any action is taken as a result. Executive staff appears at times to be completely unfamiliar with what the company even does. Salaries are not terribly competitive.
