Dartagnan, you're right on one point : no matter which FTO trained you, you'll have to pass selections to get a job.
And if OAT or FTE might better prepare their students to these selections than any FTO, it's still not enough. No job's guarantee
Assymetricdrift, it'd be very interesting for all of us if you could describe how you were prepared to your interviews and how many did you get?
Did OAT recommended you to any airline?
