Like it or not, most companies will prefer to familiarise t/prop only pilots in the RS before moving them to LS, with the exception maybe of smaller jets like the EMB145.
don't worry baby, tha's an old fashioned point of view, and mentalities are changing. Cargolux used to ask jet hours in order to apply, this is not anymore the case. And as mentioned in earlier posts, lots of famous europeen companies with a big fleet do hire turboprop captains on the left hand seat of a jet aircraft.
GSS has hired turboprop guys straight onto the jumbo, unfortunataly for you and your little friend NSF, those airplanes has not crashed yet.
