For those with limited or no experience or if CX/KA is all you can get go for it and at the very least get your free type rating.
For the ones with previous jet/command experience, unless making bunks and being treated like an idiot for the next 10 years is your sort of thing stay away from this circus.
Their antiquated tactics and approach to professional aviation (loosely used term as they have totally confused a--l with standards), may have been condoned 20-40 years ago but today there is no need to put up with this sort of crap. There are more than 200 jobs advertised on flightinternational.com.
Learn from our cock-ups and do not make the same mistake I made, it will be your worst career move ever.
