They are not calling you because you are the greatest pilot ever in the whole wide world and would put all their check airman to shame. What company wants to deal with that?
In case you dont pick up on it...that was a bit of sarcasm with a little bit of truth to it. I dont know anything about airline apps, but do you have to write a cover letter of some sort? If so, I might have someone read it as you have a bit of a cocky attitude that shows thru. An unbiased observer might be able to help you with that.
