Just a thought... If I was making recruitment decisions for RYR, I would chop and change the recruitment process as often as I could, so that I could look at candidates properly. I wouldn't want to be judging who had best adapted during the expensive and desperate 'prep' course. I'd look for the things that are important to me in a pilot, and I would do all I could to avoid being fooled by the work of an outside agency who seek to take Joe Bloggs and make him look like Peter Perfect.
Well, that's what I would do. But I don't work for RYR.
If I was about to pay for one of these prep courses, I'd fear that the employer might, indeed, be just about to start looking at candidates properly; if they did, my hard-earned cash would be wasted...
I'd like to think that the best candidates shine through any process. I did, but I didn't accept their offer. Interesting experience, nonetheless.
