I disagree very much so!
Regardless of having a PPL...
You are not 'getting into' a course like you would a job, you are going to do a course and pay your hard earned cash to do it!
Don't let anyone fool you that their 'course' is selective. They will try to make you feels that their course is the hardest to get into so you don't go looking at other flying schools. They will end up teaching you and happily take your money, so don't lose any sleep over it.
When you end up going to get anything from your first job to an airline job, the training organisation won't have any weight on the outcome, rather it is all up to how you perform, how much effort you put into your training (to get the mosy out of it) and how dedicated you are to your career, (as well as a few pieces of good timing luck along the way). If the training organisation is not up to YOUR standard, move to another; there are lots of good ones out there.
