Pros
Great team locally. Senior leadership group is solid and the company focuses on promoting from within. The significant effort that is required of you to complete your work will be recognized by management, sometimes it takes patience, but the grass isn't always greener, folks. All staff are generally highly motivated and the output shows this. Another great feature of this company is the national scale and breadth of sectors they are involved with. If you desire to construct a wind farm, for example, let it be known and you will be on your way.
Cons
This is a process heavy company and this can be daunting for mid-career project managers used to the free-wheeling ways of many companies. Multiple tiers and top-heavy structure can make it a long climb up the ladder.
