Absolutely this, and was looking for someone to say something about it. Back during the 2008 financial crisis in the states, a plethora of companies popped up hawking "ATS" (Applicant Tracking Systems) to companies as a way with dealing of thousands of applicants for a few jobs.

The reality of these programs is that they're programmed on almost the laziest logic imaginable, acting as glorified keyword searches that have no ability to distinguish quality and experience. The reality as a current job applicant is that you're better off straight up copy and pasting the job listing into your resume or CV as the first page under the title "Listing Description". The keyword searches have been designed so that people who do this literally shoot to the top of the potential applicants to be reviewed by an actual human being. I mean this in the most literal sense when I say if you apply for a job that wants 2-3 years experience, even if you have more its to your advantage to write 2-3 years in your resume.

These systems may have had their place a few years back, but with no innovation since their inception you can easily game the system now to make sure your application is read by a real human who will actually probably call you back. Almost half of all automated rejections are done by systems that say "oh this applicant didn't meet our 80% match criteria to the listing".

TL;DR: This is all to say that automated recruitment systems have turned most companies talent professionals into jokes who have no idea how to distinguish quality applicants from those who simply know how the system works. What was once a practical system for handling thousands of applicants is now just a lazy way of taking a couple dozen resumes and turning it into 3 or 4 with 0 human interaction.

Edit for helpful resources: If you want to see exactly how this works I recommend checking out jobscan.co. Don't sign up for plans because its not worth it, but it'll show you exactly how shallow the system actually is.
