Pprune is a toxic place.. and I feel like Covid has just made it worse.
There is some solid advice to be found in those bashings for sure, but if you want some true advice on certain topics (like interviews), I'd honestly just do a little bit of research on Google and see if I can find some people who went through it before. CAE is certainly not unknown in the flying industry and I'm sure there are people who are more than willing to tell you how their interview went.
Then again, any comment is useful, and if people start giving you advice and/or start bashing your ideas, it might hurt but it's always good to take a step back and listen what they have to say. You don't have to agree and you don't have to do what they tell you to do, but the more input you get from different people, the more information you have to make your own personal decisions. And if that means that you're signing up for an MPL at CAE, then that's on you.
I know, some comments are super annoying, just don't take them too personally. But keep them in mind. Some of them are good advice.
