I think some of you are reading too much into it.
I suspect that they've set a pass mark for the online tests that will give them 3-400 people whose CVs will be looked at. Of those, maybe 200 will be interviewed. Everyone below said pass mark will get a PFO.
I don't really buy into any conspiracy: not considering the diversity of experience seen on this tiny little sample of the aviation community who have already received PFOs.
I could, however, be proven wrong if everyone invited for interview has between 1500 and 2000h and possibly very limited command time: in which case, the more plausible theories will have been proven correct.
