I'm not sure if it's the norm, but I was in the June 07 indoc class and of the 26 people in the class, there were 6 or 7 guys over 60 years old and several retired military pilots. We probably had a dozen guys who had flown heavies including the C-5, 747, 777, 767/757, DC-8, DC-10, C-130, C-141, etc. and I would guess the average age was around 40-45. Also, prior experience didn't seem to have any bearing on what plane a person was assigned. There were former C-5 guys assigned to the Beechjet (Hawker) 400, and on the other end of the spectrum, there were guys assigned to the Sovereign who had only prop experience (me). It was truly a diverse mix of guys. NetJets doesn't seem to have any preference for flight experience other than meeting the minimums, being reasonably current, and having experience working in a crew environment. They're not lying when they say that the minimums are competitive. Just show them you want to be there and that you can take great care of the owners.
