Pros
Good experience can come your way if you're lucky enough to have a good manager. There are lots of good leaders.
Cons
Huge company, slow everything. Too much politics not enough action to innovate. If the whole company was on board with the new CEO's vision, it would have been a nice place to work. But people are stuck in their old ways and unfortunately the old people are the ones making the calls. People tend to manage others based on seniority instead of actually being knowledgeable on their businesses. Culture sucks. Everyone is trying too hard to suck up to senior management and is afraid of constructive criticism. Even when they do team building events it seems like an item to check off a list instead of putting their whole heart behind it in order to better the team and culture. Everyone is burnt out. Too much responsibility, too little recognition. People don't try to innovate much, because by the time the results come up, they will probably not be working for the same part of the business anyway. So most of the time its not worth taking risks and challenging the old ways of getting things done. Lots more to say, but this should give you an idea. Watch out for your back. Lots of back stabbers.
