The main problem I've found is that with the abundance of experienced crew out of work, whenever a job does become available, the companies are only interested in folk who already have the ratings. (And I'm not having a rant, I fully understand why they do this.)
I know the big companies, the likes of NetJets et al will employ non rated bods (if/when they do recruit again), but the vast majority will not give you a second glance (my own experience).
Got a lot of scheduled experience, and been trying for years to get into corporate/charter work, but not had any luck, keep hoping for this upturn some people seem to think is just around the corner.
