Pros
ICF is a company that's been on the up for the past several years, but more importantly this growth has been continuous and consistent over that period of time, which to me is a good indication.
Cons
Unfortunately, much of this said growth may depend on the individual working group and line of business (LOB). Some groups and LOBs have shown growth that is reflective of the company as a whole, but if you're in a part of a group/LOB that doesn't pull as much weight, it can be frustrating to watch. Having been part of numerous projects so far, I have yet to be part of a ICF-led project.; they have all been as a subcontractor, meaning the prime dictates nearly every aspect. I have yet to experience first hand what ICF's "culture and values" really are.
