Good question, I'm not sure, but I wouldn't think so. Netjets loves telling the owners every pilot hired by the company comes in with a minimum of 2500 hours. It's a good selling point. A pilot internship is intended for low time people.

About the aircraft insurance, do these people require a certain amount of flight experience???

I'm not against it, we loose a lot of young talent because they don't meet the mins, but I guess you gotta draw the line somewhere.
