Pros
I have never worked with so many smart people in one place! Very enjoyable co-workers with mostly realistic expectations of how much work one can accomplish. Lots of opportunity for growth. Good support for whatever career path you are interested in pursuing. Decent benefits, they have a couple of extra floating holidays, which is nice.
Cons
If you don't have strong boundaries they will gladly let you work yourself to death. You MUST be good at saying "No”. Kind-of a dreary office environment, lots of grey walls, grey cubes, grey floors, etc. They say their mission is water quality for people around the world. But like most companies, this is about making money. And they make LOTS of money. The margins here are so high it's actually a little embarrassing. As with all Danaher company profits flow directly to the top of the food chain and to share-holders.
