That requires you to get repeated attempts with the AI. Most people don't have the luxury of trying multiple job applications until they figure out how to get past the AI gatekeeper.
Or a company does this and sells the meta they learn for a monthly subscription (because as they update this on the company side the meta will change).
I saw something similar happening at one of my past jobs. The resumes were not necessarily AI-generated, but contained, in their "previous jobs" sections, a lot of copy-paste from online course descriptions where duties and achievements would go. This was caught because of two resumes with one sentence repeated verbatim.
Most companies are using the same model / llm-as-a-service though. In aggregate you can a/b test to a rough solution. In a job market like this you might be sending hundreds of resumes. Plenty of time to play the filters.
