Vantaggi
You might meet a few cool people along the way who entered the Thunder Dome (Euro Pro) as a result of being ambitious, hungry, driven professionals. These personalities are soon crushed into submission and most everyone ends up with a mild to severe anxiety disorder. But guys, don't worry, there are free bagels on Friday.
Svantaggi
Every. single. thing. (Except some nice people who are tenacious and resilient, god love them.) Folks I could list it out for days, but I'm tired to my bones. There are a million consumer packaged goods companies, there are a million places to make your mark, so pick a place where you can trust your management to be your advocate. Good people are indeed there, but the culture is so aggressive that your armour is constantly up, making it difficult to forge true connections. If you want to mirror the success of others who have battled through a couple years for the salary upgrade and hard earned experience, just have a contingency plan for the 20 extra pounds you'll gain and the time you'll need to take after this experience to regain your sense of self.
