Hours aren't really an indication of ability.
I've flown with guys new to the airline business with less than 170 hours total time, about half of which was single engine VFR stuff.
They were, then, the exeption rather than the norm but each of them were sitting in the right seat of a four engined jet and performed perfectly well and had brains like sponges ie. developed into extremely capable potential captains.
Conversely I've also flown with guys new to airline flying who had a few thousand hours in GA/Air taxi/Air Ambulance who were, shall we say, less than capable, stuck in their ways and had a distinct inability to adapt.
