how legit are the airline partnership with flight schools?

i saw a recent posting (in Canada) for air transat in partnership with CAE flight school. it’s an 18 month program with a contract of guaranteed hiring after completion to fly A321/A330 for air transat and gives a CPL + MEIR. the cost is around 120k USD and you wouldn’t need the 1500 flight hours.

i know basically nothing about this industry so i’m just wondering if these programs are legit and whether it’s good/worth it. thanks!
