I was 22 when I rushed both fighter units and heavy units. I ended up getting an alternate pilot slot with a unit and they ended up hiring people who were in their upper 20s rather than me. They told me that they are looking forward to hiring me, but because the other candidates were older than me, it meant that they had less time to reapply because of age restrictions. I on the other hand, I have plenty of time to come back and reapply to the unit. This made the older candidates more of a priority than me. Being young is a really good thing! But at the same time, you may find yourself passed over because of it. And again, it depends on the unit. Good luck!
