Microsoft

Writing software for Microsoft makes you think about aspects you probably would never encounter if you worked elsewhere, especially if divisions like Windows and Office.

Roles are more cut and dry. So if you are the kind of person who likes to just focus on the position you are hired for, the infrastructure helps you do that.

It's difficult to advance if you don't fit into one of the predefined skill sets/categories. Multifacetedness doesn't pay too much.

We are losing out on good people and ideas because there is no incentive for them to break out of their molds. In fact, because of such sharp divisions of disciplines (PM, dev, test), there is an incentive for one discipline to resist any incursions from other disciplines. I think that kills good ideas. We should look into fixing that.
