As one who went through the idiocy of the Mr PhD know it all guys little gem of a system back in 2011/12 let me throw one piece of advice at you. I found out his "system" had kicked me out of the 'little' pool (i.e. should have gotten a call because I had be vetted and approved to get that call from the 'humans' who look through them). I wasn't the only one in '11 either. So I foundered all summer of '11 waiting on a call that never came. Through some friends found out in August that in fact I was "out of the pool" - and had to make some phone calls and sponsor got involved. They didn't "know" at the time what happened but they "fixed" it and in September I was told all is well - I'd get a call. They stopped/slowed hiring for peak and I got that call in Jan of '12 instead of summer of '11. His system is - to be blunt - stupid. It has nothing to do with hiring the right pilots but with insuring companies can cover their six for whatever the insurance/PC requirements of the day are (Delta uses him too - went through that 18 months before jumping to FDX). So beware of the lunacy of certain companies and their hiring 'system' - its not as straight forward or clear as we'd hope or believe what's being advertised. Why you aren't getting a call can be for a wide number of reasons. While I'd caution anyone on hounding the hiring department, getting a sponsor involved, an occasional phone call 'asking' if things look good - "might" be in order. Squeeky wheel does get the grease after all. Just don't over do it. 2 cents.
PS - I found out what happened with the idiots system. Criteria was set that essentially said certain resumes couldn't possibly be what the applicants said they were so they just "kicked them out" without informing anyone. He'd better hope we don't run into each other in a dark alley one night...
