A current research discovered AI-powered applicant monitoring systems, or ATS, not solely prefer AI-written resumes over these composed by people — they’re more prone to put candidates on the short checklist in the event that they used the identical massive language model the company already employs.

They then simulated hiring pipelines for twenty-four occupations, and located the AI evaluators have been 23% to 60% more prone to choose candidates which used the identical LLM.
