that's an awful application to interview ratio, jeez
(my main empathy will go at the recruiters, having to filter out massive amounts of auto-generated applicant files!)
because it's an arms race, recruiters are also using AI to filter people, just look at the chat GPT hack for resumes
Doesn't even have to be anything big, just that there aren't enough keywords, or that there were gaps between employment that were too large, etc.
The ATS would then rank the applications and score them, and HR just looks at the top 15 or something and picks the top 5, whittles them down to 2-3.
They're not spending 8 hours a day reading resumes.
