Avantages
Mostly friendly, but you soon discover that if you don't fit the "culture" exactly, you will go nowhere.
Inconvénients
The leadership "development" hinges on your peers communicating their perceptions of you to senior management. You quickly find that you must be constantly aware of how others view you because those views go directly to senior management. When that happens, you begin the struggle of perception management, even though it's often started by some peer who has never worked anywhere else. With very little management experience or experience leading people, these brand new managers are given the false impression that they are leaders who can judge the abilities of peers. This becomes the "machine" of the culture that each "team" member must survive in.
