Microsoft

Developers have their own offices.

Because Microsoft has a longer release cycle than many software companies, the stereotypical "have to work overtime because the project is due" doesn't really apply. It's a very laid-back environment.

As long as you get your work done and don't miss meetings, no one really minds when you work.

As with any company with thousands of employees, sometimes you can feel like a grain of sand on the beach. As a developer, you don't have a say in the big picture of the company. If that's important to you, don't work here; find a start-up.
