Pros
Good benefits (but average for a big corporation) Good exposure to co-workers from many different countries. Interesting work if you are lucky enough to get in to the right group, or can make friends with influential managers. Many co-workers care about the job they do. Finally realized Harrisburg offices were huge dumps and began remodeling them. Results are much nicer office space.
Cons
Small town Pennsylvania is not the center of the universe like many think. Below average salaries for a large company. Never enough people in IT to get the job done. Senior management outsources work but does not have to deal with the poor results. They make the big decisions, then walk away. Remaining employees are left to deal with these new headaches in addition to their own jobs. Outsourcing company uses people on a different continent who can't communicate in understandable English. Work load is too high and projects are rarely refused. You are being judged at all times. Lots of cost cutting. I'm sure senior management will cut medical benefits the first chance they get, and then brag to Wall Street about good financial results.
