Are you applying to only fighter units? It seems a bit peculiar that you have only had one interview with those credentials. I applied for three months, got two interviews, and was just selected after my second. All with scores lower than yours and considerably less hours with only a PPL.
I would say that if you aren’t already, apply anywhere and everywhere if you really want this. For myself, I looked at it as a “beggars can’t be choosers” situation. Also, I think you need to take another look at your cover letter/resume/LOR’s. I would be happy to review and give advice if you are interested!
