Be VERY careful, what is the 'guaranteed" job? There are jobs and "jobs" i.e. are you going to get a jet rating and a proper job as an FO with an airline or are you going to become a flight instructor with the same company and for how long…with what prospects?
I would be VERY surprised if it was a jet rating and a job as an FO, and if its as a flight instructor you can do the same much much cheaper.
If they were actually offering the rating and a FO job position within an airline they would be inundated with students. There is NO easy way into this industry unless you are lucky enough to be a cadet with Emirates or the like.
Unfortunately the training market is buyer beware, it is bad enough in Europe getting a job but the UAE is much more limited for ab-inito pilots.
