The assessment should be the same, more or less..
The difference is that (in that day) there are only APC assessments, so there should not be anyone with a lot of experience and someone without.. The level is pretty much the same for everyone, but everyone comes from a good preparation let's say, as it's the flight school to choose them for this program.
PLUS, in case of positive feedback, you don't have to pay the TR, but the company pays for you and then they take from the salary every month.
