I've just posted about this on another thread yesterday:
We've seen threads with (alleged) HR professionals claiming, "why wouldn't we screen with AI? It makes our job easier!" then they're also complaining, "why are all the CVs these days written with AI?"
They're not making the connection that the AI screening tool is binning more of the CVs written by humans (which are the ones the HR professionals actually want) and leaving them with more of the CVs written by AI (which they don't want). This is one reason (out of several) that it's so hard to find a job and a good candidate right now. People are getting desperate and blanket-applying with the same CV and that's no good as a tactic anymore, you need to rewrite every CV specifically to each new job application (and definitely with the cover letter).
I ran my CV through one of these AI CV checkers and was shocked at how poor it was compared to the AI that I work with daily. It couldn't tell that different verb conjugations were the same word, so it said I didn't match job descriptions when I actually did and any human would have seen that straight away, because, for example, I stated I had "organisational skills" and the job description stated "must be organised", and in another case I stated I had experience with "data analysis" and the job description wanted "data analsyis" (which was a clear mistake but the AI just blindly decided my word didn't match the word in the job description and told me I wasn't suitable for this job).
It's obviously a terrible AI design but this is one of the most popular AI CV screening tools on the market; on their website they had a scrolling list of major companies that use them. It also had no option for British English so threw up a load of typos that were not typos.
If you don't 100% match the job, it throws up that you're not a match and highlights a laundry list of your "missing skills" even if they're actually there but in a different verb form or spelling.
This leaves a dilemma, do I fix the CV for AI then risk a human throwing it out because it now looks like it's written by AI, or do I leave it as is and hope any given company doesn't screen their job applications with AI? Because not all companies are screening this way and you don't know who's doing it until you apply (usually).
Just bunging a load of keywords in doesn't work anymore (not sure it was ever the best plan) for the reasons above.
