Just as counterbalance. I know of at least half a dozen small operators that will not touch someone from the top 3 FTO's because of bad experiences in the past when the world was CAP509 or self improver. Its an unfair world. I also know several flying schools that only ever hire instructors who have trained with them so by going down the OATS/BAE/CABAIR route you exclude yourself from some high turnover flying school instructional posts.
That said, when GB or the likes do pick up the phone, its very nice to be in the right place at the right time. Bit like buying lottery tickets every week though - expensive and very long odds.
Choose yout training based on your needs, your stregths and your budget. Forget about employability post graduation as there are so many variables its all down to luck.
Good luck,
