Pros
A good environment to meet people young in their career for networking purposes, VERY smart and supportive COO, You can make your own career path if you are well liked.
Cons
The leadership is lacking, lack of organizational structure, good old boys network heavily favored, leadership lacks ability and skill to lead others, opportunities only come to favored employees, revolving door of HR, VPs are treated like gods by the CEO (they get trips, and retreats, while regualr employees get pot lucks and apps paid for at Happy Hours, unless the COO pays out of pocket)
