Re cadet schemes nowadays. Assuming the cadets will go straight into the RH seat or supernumary seat of a jet transport. That these pilots lack real flying experience in the world outside their flying school probably doesn't matter anymore. They will go straight into a simulator for their type rating and will come out of that with a command endorsement or perhaps a copilot endorsement. Their SOP knowledge will be superb by the end of their simulator training.
Their line training on the real aircraft will be 99.9 percent on automatic pilot just like their simulator course. If on long haul they may be lucky to get one take off and landing every few months and that will be after switching off the automatic pilot shortly before touch down. The manufacturers realise that inexperienced pilots will inevitably be flying their aircraft and that is why automation is accented from the start of the very first simulator session.
The opportunities for these cadets to gain experience by hand flying in jet transports will be few and far between so that is why it doesn't matter if an experienced former GA outback charter pilot is the first officer or an inexperienced flight academy cadet is first officer. As long as they are both red-hot on the automatics is all that counts in todays airline industry. It might not be the ideal situation but it is the norm nowadays because the automation is so reliable.
