Pros: appears to be a diverse workplace, some big company benefits
Cons: scattered it platforms, top-heavy management, losing many qualified personnel
I'd recommend staying away from Arcadis (or ARCADIS as they insist it is spelled). My office, the largest in one of the top 10 metro areas, has lost at least 25% of its personnel in the last six months. Some have left on their own, others let go or 'furloughed'. Specifically, the Environmental remediation and industrial hygiene divisions seem to be bleeding personnel. Yet, they look for replacements for people who were let go because of slowing work.
Arcadis is the result of many mergers and the company is still not integrated. In particular, there are overlapping, redundant databases. Being a larger company, there is an extra 2 to 4 layers of management which add to client costs and makes it harder to put together a competitive bid.
Arcadis does manage to hire a good percentage of women engineers and scientists, perhaps being the company that is closest to gender parity in this type of business. That is not easy.
In general, a job seeker should be very wary of Arcadis.
