Vantaggi
Staff typically start out as an interns, or some form of it at WWE... Which gives you great exposure to so many aspects of production that you wouldn't otherwise have at many other production companies. Writing, producing, directing, and editing are all part of your first year at WWE depending on the department you are in, and to the level at which you perform... So if you keep your chin up, your mouth shut and let your work speak for itself, you will succeed at WWE.
Svantaggi
It can be a very toxic work environment at times with a lot of turnover, I spent over 9 years with WWE and while I do owe so much of what I have to my experiences at the company - I left because I couldn't deal with the political game that seems to be played there. I found myself participating in the nonsense because the job made me so depressed. When the stress, and politics wear you down to the point that you no longer enjoy producing creative content, it is time to move on.
