I know plenty of more than able pilots, that would fit the BA mould and much experience, who would be happy to join BA!
However from the start of making an essay and Aptitude tests before you get to the interview stage, they are not even bothered to apply!
There is a lot to be desired, and we do not live in a perfect world! That some basic computer game from the 80's decides what way you career is heading is for me beyond a joke!
But those are the rules of the game! I seriously doubt that there was somebody from background from aviation who seriously promoted these obsolete games, however there are HR companies who needs to make money, so they create such products first to the companies for their recruitment, and then training packages to the applicants!
End of the day, it all comes down to MONEY!
