Pilot is one of, if not the, most competitive job in the ADF. Applying just for pilot can show a motivation just to fly, as long as you can back it up by proving you have experience in/passion for aviation. I applied just for pilot, and I had no issues. Don't apply for another job for the sake of it; think to yourself, if I ended up getting my second or third preference, would I be happy having to do it for up to 14.5 years?
