Pros
The individuals that you work with are very friendly and competent, office management treats people well. Employee resource groups are active and engaged, so there is a good sense of inclusion for (some) minority groups. Benefits and work flexibility are good.
Cons
There is a HEAVY corporate hand and it's all about profit: Huge emphasis on utilization with higher goals than other environmental companies, there is not enough work to make those goals. Rounds of cuts happen every year and the approach is cold-heartedly corporate. You will be blamed for a situation that is not in your control. They will try to force a resignation, presumably to keep unemployment insurance costs down. Seems like KKR is trying to squeeze as much juice out of the fruit as possible, like a typical investment firm. Best not to join until KKR is out of the picture.
