Pilot Pete is spot on.
It is not all about having flown for 20 years and knowing the aeroplane inside out.
Must of us here would agree that there are guys out there even today that act as single pilots.Happened to me. Non standard calls that I have never heard of before, CRM -what, and that sort of thing. Also attitude and personality count more than experience especially when you put someone in unfamiliar teritory, you can really see ones ability to delegate and be delegated to.
My two cents worth.
