It’s so dumb. There is no way to verify the numbers, and yet, this stupidity weaseled its way into the LinkedIn cinematic universe of corporate bullshit. The same point but without the “X by Y%” hits the same for me— besides I know what questions to ask to judge if you are actually capable of moving the needle, which is all I care about as a conductor of interviews.
the problem is CVs are screened by non-tech HR/recruiters, who lack the capacity to screen candidates. Because it is much easier to apply online with one click, each position is spammed with millions of CVs.
in response, for HR it is much easier to filter out CV if it lacks style, not substance. Therefore they look at bullet points like "Done X by Y%".
The proper way should be to limit the intake funnel: accept only a few applications per job, so that they can be screened properly by HRs by calling them, and talking to them and properly screening (old school style), instead of tossing their resume to the bin after 15 sec quick review
