Recently had an opportunity to sit in the "sharp end" of a Flexjet Lear 60 in the States. Wow! Quite a view - I encourage anyone who is interested, and has patience to put up with their frustrating human resources process, to apply. The pay might not be phenomenal, but the aircraft sure are (Lear 31, 45, 60 and Challengers 604 and Global Express)!
I don't work at Flexjet, but I have a number of friends who do who really enjoy the flying. The prospects for getting into the LHS of a Global Express are good in the long-term.
Happy Flying!
