Has anybody ever thought about what an airline's selection team are looking for? If you are given a profile, they expect a reasonable attempt from candidates in showing they have tried to learn it. Then they want to see the poor sods in front of them can learn and show improvement. Lastly, they want to know they can spend a day or two with these particular space cadets. Nobody cares if you did a JOC or hyper-active dogwalking course - what matters is what is presented on the day.
