This guy sounds like he's reading off a script prepared by the Chinese government. Whilst domestic air travel in China is increasing, most of the foreign pilots were laid off or given LWOP, those remaining are increasingly on local terms rather than the high $$$ contracts which got them there in the first place. Moving to China was a big gamble due to the high failure for medical and sim ride, agencies used to send over any pilot they could get their hands on who met the minimums as the percentage that got through was so low. Then there was the issue of commuting or moving families there.
All Bain need to do is offer contracts to the exact number they want moving down the list, the percentage that sign will indicate the "no show rate". They then make up the shortfall in round two by accounting for that rate eg. send out 200 more offers if they need 170 pilots. Job done.
