I'd go for P&G if I were you.Starting and running a business requires management experience, which you don't get in consulting (esp. at MBB) until several years into your career.GS and PE will get you some good contacts for raising finance, but you'll miss out on learning how to run a business, innovate, etc. If you've all those offers, you probably have sufficient networking skills to raise finance without working in the finance industry yourself.Google fits the bill for getting hands-on experience. However, exposure to the real decision-making is by all accounts very limited outside of a small clique in Mountain View. If (like most forum members here) you're looking at UK positions, I don't think you'll get much out of the job apart from an interesting CV - if you're looking at starting out on your own, that's an irrelevant consideration.P&G will at least get you good exposure to how to be successful in retail and consumer goods.
