If wannabees are such dimwits that they need to be made to feel they are elite in order to get them to train as a pilot...well, that's the best argument I've heard yet for why there ought to be some selection tests.
Surely the point of selection is so that the large FTO's such as OAT and CTC can sell their product (the trained pilot) to the airlines. CTC have a low acceptance rate for their cadet scheme, therefore they can ARGUE that their trainees are superior to competitors because they have carefully selected those who are most likely to succeed. This is what these organisations rely on, they remain selective so they have a basis to argue their case that they are indeed producing the best trained pilots (whether that is true or not can be and has been discussed elsewhere) in the industry because they are selecting the best candidates from the start. The rigours of the tests then hopefully gives the partner airlines confidence in the cadets being put forward by the FTO for jobs.
To the OP, Apply for CTC Wings. Your 22 so you must have had some experience working within teams? If you haven't, think about what you could have done differently in your OAT assessment, try not to be too dominating and just get stuck right in. For their group exercise, all they are looking for is for team players, not airline captains (start worrying about that in about 10 years). Also CTC is only a 1 day assessment so it's all over quickly. When I did it, we got the group exercise out of the way at the start of the day. If you say that your other skill areas were good, the rest of the day should be a piece of cake!
