And honestly, raw numbers will tell you nothing. Yes there might be 40 engineering majors in the chapter when you pledge, but they might all be seniors graduating in December (extreme example for effect).

You're thinking of networking through the sorority in a very very limited way. The person who gets you your first job might not be someone who had anything to do with your major, but might be someone in a major completely opposite from yours who put you in touch with people in your field of study. You'll be happier if you join a group of girls that you truly have affection for who can help you with all aspects of your life, rather than just trying to find people in the same major as you.
