I was knocked back by CTC at the interview stage in 2006.
Moved on, got a well paid job still within the aviation industry (albeit ground based) and now have enough spare cash I could finance my training upfront without going into debt and guess what... not interested anymore. Been in the industry for nearly 4 years now and like everything else, a job is a job and your life is more important after work, what you do with your time, friends and family, and I look at my CTC failure as a blessing in disguise now.
Granted, watching the sunrise from 39k feet is a privilege, but then again, it wasn't meant to be, and there are pretty views from ground level too
