Pros
Good pay, good benefits, good job security, office culture is generally pretty relaxed. They say that work/life balance is important, and they mean it. You can have a lot of flexibility as long as you get your work done. There are opportunities to work almost anywhere in the world. Most managers are easy enough to work with and care about your professional development. The upper-level leaders are really committed and seem to do a good job. The new CEO looks like he'll do a good job.
Cons
The corporate stuff is annoying. It takes forever to move projects along or make decisions because a million people have to review or approve or something. It does matter who you know, even though they claim it doesn't. People who are identified as 'high leadership potential' get promoted at lightning speed, even though the process is supposed to be equal. There are some incompetent managers in middle management that make you wonder how on Earth they got there. If you're unfortunate enough to get one of those, your satisfaction with your job can go in the tank, fast. The feel-good nature of the company means it can be difficult to get honest feedback sometimes. It seems like no one wants to hurt anybody's feelings or say anything negative. People who have been here a long time are almost like robots. You can see it happen as the new hires get indoctrinated into the culture. If you put together any halfway decent piece of work that wasn't directly required, people act like you're a genius.
