I hate to be the "buzz-kill" but there is no such thing as guaranteed employment.
Promised employment-maybe or the possibility of employment.
What kind of employment can a school promise?
How would a school know when XYZ Airlines needs FO's?
They don't.
It is very difficult for a school (in the USA at least) to predict how many Instructors they need in 6 or 9 months.
Unless they have a pyramid scheme in place where they hire, then fire when the new "batch" is ready.
Usually limited to residents of that country for one easy reason; legal employment.
