In the end, buddy, its all about closing the sale(by closing the sale I mean selling your skillset as an asset.) If you are confident and cool then you can b.s. your way into all kinds of opportunities. It partially depends on the industry you are trying to get into, some industries are diligent about checking credentials, others not as much. There is a sweet spot between looking so good its hard to believe that you would take the job you are trying to get, and on the other hand, just barely having the right set of credentials.
