@Check Airman:
Not sure if pilots you hire are Chuck Yeager's relatives or your standards are lower, but I can't imagine many people who could successfully to from zero airline experience to being able to competently operate a jet to the standard we require on the line in 25 hours (unless those would be sub 1h flight times) - at least where I work.
Pilots new to airline flying are usually drinking out of a firehose, as everything is new to them. From check in, weight and balance, paperwork, PAs, etc. - let alone flying an aircraft 40 times heavier what they previously flew. And there's so many things to cover, Cat 2/3 approaches, NPAs with various levels of automation, manual flying, etc.
Seasoned captains with experience on type? Sure, couple of days so they get used to the different papers and checklists, and off they go. New first officers whose last aircraft was C172? No way.
