The salary isn't anything fancy, it's alright to put food on the table and roof over head pretty much, but there are some benefits (travel benefit, relocation benefit, LOI, etc.) and one have to consider it's a bonded sponsored program when looking at the salary.
But yes I believe the goal for L3 with all the instructors they hire is to fast track them to ME IR instructors as quickly as possible, but I'm not sure yet, time will tell and obviously I'll have to perform well!
