This is going to sound harsh, but people should absolutely not be failing '4-5-6 exams on the 14'. The subjects are not diffucult, there is just a hell of a lot of information, and if someone doesn't have the time, the resources, or the will to get their head down and pass the vast majority if not all their exams at the first attempt, they should save their money and concentrate on a different career. Of course there are sometimes slip-ups and unexpectedly difficult papers, but these should only ever result in one or two not being passed.
Whoever thinks taking several months to study for and then sit fourteen exams is hard, they're going to get a big shock when they get two weeks or even just one to both pass a type-rating ground school and do sim prep at the same time.
It's a tough world out there trying to get a job. When it comes to low-hours pilots airlines are likely to recruit: First, those who know someone or have been recommended, and second, those who did extremely well in their courses and are the least likely to present problems in training.
