I got invited for an interview yesterday, with even less qualifications than you.

I have 850hrs and a couple more checkride failures. I am eligible for the 1000 hr R-ATP.
I am an ERAU Alum, maybe that played a role, but otherwise I can't see why they would deny you when you're a great candidate

What is your education level? It doesn't really matter in this industry, but like the above post said, maybe you weren't competitive in your applicant pool because of it.
