When I worked for a charter operator in UK we recruited both ex military jet pilots and ex C130 pilots.
The C130 pilots usually made a seamless transition, being well up to speed with the crew concept and adjusting to the different airraft speeds very quickly whilst some of the ex military jet pilots could handle very well, (though not always as one would wish a commercial jet transport to be handled!), but had little or no idea about the multi crew aspect and had to be trained out of the one armed bandit regimen.
