AI in hiring
67-82%
How often a model preferred its own writing to a person's.
Software rewards machine writing. People do the opposite.
Across 24 simulated occupations, language models preferred resumes they had written themselves over human-written ones of matched quality in 67 to 82 percent of head-to-head comparisons. A candidate whose resume came from the same model the employer screens with was 23 to 60 percent more likely to be shortlisted.
What this means. This explains the pattern I hear most often on first calls. You get through the screen, then nothing happens. An AI-written resume can clear the software and die with the human who reads it next. Write for the person who decides.
