What OP needs now is Turbo jet, high altitude, advanced automation experience. Not paperwork and history of passed checkrides. If he takes the caravan gig buzzing around <10,000ft at 150kts he'll whined up in the same situation he was last time. Behind the airplane and another failure. Take the jet gig and get a well rounded understanding of operations in the Flight Levels. Arrivals, approaches, callouts, FMS work etc will set you up for the next 121 event and can Guarente it will give the hiring team more confidence in his ability to pass. At the end of the day OP has still never flown a JET.
