I was also rejected. I have PPL flying experience and felt i portrayed my passion for the industry pretty well. Certainly feel like I have 'earned' the right to get through to the next round but sometimes things happen for a reason.
Although I am sad about not getting through to the interview stage like others have said it only makes me more determined to make it work. I also believe a small element of luck comes into it on these applications. They read 5000 applications and have to get it down to 100-300, numerous guys/girls that are completely capable and passionate will still have to be rejected so I am not letting it put me off applying again. ATPL modular or perhaps whitetail has its advantages as well. Regardless of the route people take, if you want to be a pilot and you have the drive you can make it happen.
