Pros: It is a big company and hence there is job security to some extent. Your experience would vary depending on which group you are in. Some great mentors to work with, from whom you can learn a lot. There are a few people who make the company worth working for. You will get to work on really large products with enough challenges and opportunities to learn. If the group is flexible, there might be opportunities to try out different roles and see where your true interests are. However, few groups are open to it, as they would prefer you to continue in your role to avoid potential time delays to product releases.

Cons: Each group has its own management/promotion policies. The group I was in did not promote my career growth. For several years, there were no raises or bonuses. Be it in a technical track or a management track, the career path is not well defined. Again, this was in one group, but I have heard of employees being very happy in other groups. I would strongly recommend talking to more people in the group you are joining before you accept the position. During the interview process, do request time with the rest of the team and talk to your peers to get a good handle on what the job is about.

Pros: Decent pay. Work was rarely stressful. Great mentors to learn from.

Cons: Hard to find challenging work. Little to no innovation. Slow-moving development. Primarily shifted towards maintenance work.

Pros: I was able to telecommute, and that was a huge benefit. (I can't imagine why anyone who isn't a recent college graduate would relocate for a job anymore.)

Cons: There was no actual innovation. Most of the technical discussions were about curly braces and indentation, bug triage, and arcane recipes for reproducing bugs. Some people enjoy the reassuring stability of doing similar things over and over again. Not me.
