Where do I start?
If you're a young, motivated Millennial that wants to move up fast and have the opportunity to progress and contribute at a fast pace, don't bother. This is sloth like company whose logo might as well be "we've always done it that way". Most people here are at or beyond retirement age and are literally counting the down the hours. People are overall very unhappy, cynical and resigned after working here 20+ years and seeing the company continuously cut down on benefits.
Management is a joke. Actually, most engineers end up sitting around comparing management to Dilbert cartoons. Most have Dilbert cartoon snippets cut out and posted around their cubicles. Essentially, all management does is go to meetings to figure out what other management wants them to do. The entire thing is fascinating to watch because most are in there just staring at their blackberries. When done, they will return to tell their engineers what they need to do and when they need to do it by. If no, they will look very bad to the 6+ layers of management above them.
If you're lucky, big if, you'll actually get a chance to do some exciting engineering work. However, you will most likely be a giant paper pusher updating spreadsheets, online databases and answering emails and churn about your "status" on a particular item. This could easily become 50%+ of your life here. You are not an engineer, you are a Microsoft Office+PowerPoint+Excel expert!
Bureaucracy is comparable to the U.S. government. They might take tips from them I think. And if you have an issue, well, this isn't an open culture. Boeing is a very, very passive aggressive culture. No one here speaks about the issue, they just talk around the issue so conflict resolution is non-existent. Then again, I speak purely of the engineering environment. Other areas could be better or worse.
