It's unfortunate but I guess your always going to get those people who never really had any motivation at school and suddenly want to become a pilot after seeing an advert on fb. We have to be positive though and show aer lingus that we will be better pilots!
There is no scientific proof that if you wanted to be a pilot from a young age versus stumbling across the advertisement and decided to apply, you will be any better in training or have better aptitude for the skills in which the job demands. That is a myth.
