I think there might have been a genuine recruitment opportunity here although young Carl may have over-egged the pudding somewhat. I suspect however that a combination of factors led to his downfall.
The fact that he has now "moved on" would very strongly suggest that his vocal and deliciously unprofessional involvement & interaction with this forum did not go unnoticed by others, including I suspect the company looking for pilots. If I was an airline recruiter I would not wish to be involved and/or associated with the petulant comments he was making on here.
I think people really have no idea just how many people & institutions read and are aware of ongoing subjects on Pprune. Poorly thought out comments on here will bite you on the arse one day.
