Pros
You can work overtime depending on the site and client, paid hourly if you're not a supervisor, make straight pay overtime. They provide training like large companies do. Not my experience, but with the different site locations and various clients, you could have various types of experiences with Arcadis.
Cons
You may feel like a number as they are constantly expanding. There are good people here, but the connection has not been strong for me. Depending on the site, you will not travel even if they say you will. Supervisors may hold onto employees without providing much incentive because of shortage of employees. We should get paid time and a half overtime, especially working in the field. Unless you have decades of history with Arcadis, you will not get time and a half, even working weekends or night shifts.
