My two cent on the young punks with CPL or MPL ...
As far as I know there is still no possibilities for a MPL to get a ATPL without later doing the full CPL + PPL PIC time building. So for any companies with a good load of CPL and ATPL's go for MPL and one will have FO's with MPL stuck in the right seat for a loong time
.... (And the thing on the MPL is that the punk is stuck to, Licence only valid with host airline so little or no chance the fu..er leaves for greener pastures
