The process took 4 weeks. I interviewed at Arcadis in Nov 2010
Interview
The first interview was fairly straightforward--asking me about some of the points already listed on my resume. The second one went well, but lasted for a while--it was about an hour long. They gave me a hypothetical situation in which I needed to explain how I would find information about a given site. They commended my answer as being resourceful.
I applied through an employee referral. I interviewed at Arcadis

Interview questions [1]
Question 1
