There's a problem with HR software
According to recent reports its not you but the dumb software that HR departments use to manage job applications. Its actually an object lesson for all of us about what happens when sophisticated software -- or should I say "ostensibly sophisticated software" -- is put into the hands of dumb users. We've had ample warning about this because a simple search on 'resume hiring problems' will bring up numerous sites offering tips on how to make your resume stand out (many for a fee....). Put another way, the only way to get hired is to know how to game the system, know how these software packages work and how to game them.
The perfect storm is created by poor qualify filtering combined with ridiculous job specifications. One example quoted was for hiring nurses -- qualified applicants were being rejected because the job specification said the applicant needed to know "computer programming". Relatively few nurses are also computer programmers but I'd guess that practically all of them could enter patient information into a computer, the actual skill needed.
FWIW -- This has been brewing up for years. Back when I was a hiring manager I had some serious coups by gleaning the HR reject pile. I needed people with technical smarts, in fact one of the very best hires I ever did was someone who I will willingly describe as the "World's Worst Resume Writer".

PS -- As a final aside many years ago I was hired into a position where I was "absolutely essential" for the job in hand. As one of my hobbies is "industrial archaeology", i.e. going through abandoned filing cabinets to see the what, why and how of floundering projects, I went through the filing cabinet I had inherited only to find a copy of my resume I had sent in months before (and got no answer from). Apparently the company needed a paid recruited to soft talk them.
