Pros
The previous review hit the nail on the head. It's a paycheck. Big company, so you can always find people you like and enjoy working with. It's good if you like a monotonous workplace. A negative to some, to be sure, but it is nice to always know what you're going to get. There are very few surprises.
Cons
For some reason a decent percentage of lower and mid-level management seem to be poorly suited for the job. My manager was friendly and positive, but clueless as to how I did my job. The pay is okay, but opportunities for advancement aren't as plentiful or fairly rewarded as you'll be told in the interview. There are A LOT of meetings and I swear I've been to meetings to discuss if there were too many meetings. It's not a bad place to work, but it really is a gray cubicle environment and that wore on me over time. When I put in my two weeks I had about half to 75% of the people I work with admit they hated their jobs and couldn't wait to go somewhere else.
