Vantaggi
Depending on the team you're on you will have about 5 hours of work a week as long as you're good at politicking. But then again some teams are worked so hard that people literally developed health issues. Good luck.
Svantaggi
A lot of your career progression will come down to are you "playing the game" correctly. As one manager put it "It doesn't really matter what work you do, what matters is the perception people have of the work you do." You will likely have 15+ hours of pointless meetings a week. You will need to learn to document everything you or you will likely be blamed for problems you had nothing to do with and have credit for your successes stolen by others. If you don't mind endless bureaucracy you can make this all work for you. They've already started layoffs without calling them layoffs though, and doing a good job has almost no impact on your value there.
