Understand the frustrations. But Singapore Airlines, BA are examples of airlines with cadet programs starting with zero hour pilots. However, because they are zero hours, they are technically a clean slate not tainted by any substandard procedures that may have been used as examples but indoctrinated in the culture of the company. That being said, the premise has to be that the company already has a strong foundation in the said SOPs, FCOM and CRM culture for that to be true.
So having 'jet' time or previous experience is only good to the point on handling skills and SA building. Once it becomes intrusive in benchmarking SOPs to what was familiar and not necessarily the most ideal method...then it becomes a different story
