My understanding is that HNA will be doing their own hiring, w/o an Agency. At least for pilots from the US, as that's what I was told... I will submit all the paperwork with the CP and see were that goes. Make sure that u have no rest in your Type, at least a 4 year deg from acc university, and all the FBI/Police records notarized by the CN embassy, etc.
I am with a Sub of HNA group, so this might not apply to you, but QOL and everything else is EXCELLENT for us!!! Keep on doing research and you might find a few HNA pilots as I know that they have several foreign p's... And they should be hiring more that 50 or so.
