I don't ever remember being asked my GPA in my Delta interview or if that was on their 6 page app. This was a long time ago, I guess now they are looking at it. Mine was not spectacular, that's for sure, about 2.5, if that, I think!
I was asked about it at my 6 man Guard Interview Board. I said I'd been very busy flying 6 hours every night during my last two years of college. Then they asked why a girl with only 10 hours scored higher than I did on the Air Force Flying Aptitude Test.
I just burst out with a laugh and said, "That must be some test! Tell you what, put the two of us in a simulator, turn the vis down to zero, and let's see who can find the runway..."
Of course they hired the girl with 10 hours.
Turns out she had been a Captain on Active Duty, and worked in the same office where the tests and answer key is stored. Imagine that.
