It is not what you know that matters rather who you know.

I just got to know that some of the nastiest, most arrogant, inconsiderate people in the design center of the organization which I work for have been promoted to directors.
I personally felt that some of these people do not even deserved the engineer position much less a promotion to lead important functions within the design center. All that some of these nasty people do is just talk and no action. Some of these people are very good in indulging in office politics and currying favors with their upper management.I suppose after all said and done politics rules in almost any situation.
Sometimes it is not what you know that matters; rather it is whom you know that matters.
