I have just finished a year contract with EF in Bali - what I read about them on the internet before coming was generally correct. It's definitely like the Mcdonald's of English schools! People see the 'EF' logo and think it's an assurance of quality - it's not!
What exactly did you hear? And have you applied at any of the schools? I personally think the online schooling they have is mind-numbingly boring (I escaped as I always had a full schedule - they make you do online stuff if you are ever under your MAXIMUM hours i.e. 24 contact hours - clever, eh)
I should point you over to this site - omniprof.ning.com as it is like a social networking site for teachers. I have also been adding some blog stuff about teaching in Indo / Bali. Check it out!
