I am 15 years into my tech career and I have never heard this acronym.

Does gaming the shit out of recruitment process counts as "rudimentary effort into creating a CV" these days? Because I can't imagine how the two would otherwise be related from the job-seeker point of view. It's a backend-side system.

If anything, my closest encounter with something like this (but without learning the acronym, until today) would be those companies that told me to take the CV I put so much effort in, and copy-paste it into a textbox on some website. Or, even worse, copy-paste pieces of it into couple dozen different fields across several pages of their shitty webform. I stay away from companies doing that.
