I'm not a NetJets pilot, not even in turbines, but being in GA I have a lot of the same pressures they suffer, and I chat with a lot of them who I meet at various handling agents. I can see NJ captains being rather overburdened to have such an inexperienced FO flying with them, pressured on the ground and in the air by having a lot less support.
We learn a lot in our first 1500 hours - I am there, and can apply to NJE so do not have any axe to grind. I just have seen the struggles of inexperienced pilots I have line trained in our business, where inexperienced is "over 700 hours with a minimum of 400 hours P1", not "180 hours plus a type rating, 80 hours P1, some of that SPIC".
