Pros
The people are really the best...colleagues, support staff, management...if you take the time to build your personal networks and take personal responsibility to gather information you need, you can be very successful and satisfied. I have yet to find anyone unwilling to talk to me or give me information or support. In my experience, management (individual and as a group) genuinely care about the staff and the company, but may not always have the time to communicate to each individual or the power to make significant changes for that individual when they must consider the total population and equalizing performance and reward systems.
Cons
Like any growing company today with a responsibility to shareholders, business metrics are demanding and high pressure environment is everwhere, every day. However, unless you have some kind of dream job somewhere, I don't think it is that different than any other economically challenged company with productivity requirements to make the bottom line. Like many companies, ARCADIS is what you make of it. If you go in with a negative attitude, or don't take charge of creating a rewarding experience doing everything you can yourself, you'll be very unhappy here or anywhere.
