Probably not seeking qualified people from outside their preferred network. The problem is many companies will hire from a selected group of universities and majors for their technical staff and ignore anyone who is competent but lacks the degree from the "proper" school. I would not be surprised if Facebook is not doing the same.
What happens is the pool they choosing from is not very representative of the whole pool but instead of looking outside their pool they moan about not finding minorities.
