I don't want to sound like a bitter wannabe cadet but I went for the interview last year and didn't get past 1b. I started training for my PPL in high school with about 100hrs, went to a top University for economics (irrelevant but still should be considered), I've had an internship working for the largest aviation oil and gas company in the world, I volunteer with the air cadets and teach ground school. I genuinely have a passion for aviation. They took someone who was studying to be an accountant.
