I don't think there is any real path to becoming a VIP/Corporate pilot.
Licence wise you will need CPL or ATPL + IR (this is the minimums for many corporate flight departments). All depends on the machinery being used.
That aside, personality and being able to put up with the mundane is a big advantage PLUS who you know.
Apply for every corporate job going.
The toys that Capt. Hollywood shows us are there for some of us it's just I have no photos of them (except my trusty steed).
ALOT of waiting around as well!
