With more applicants using LLMs to draft resumes and cover letters, many HR departments are turning to automated tools. But would you actually trust an AI detector for high-stakes hiring decisions? I’m concerned that candidates with a strong background in Cyber Security or technical writing—who naturally use structured, precise language—might be unfairly flagged as bots. Are we risking losing top-tier talent over a software’s "probability score"? I'd love to hear from hiring managers: do you use these tools, or do you find them too unreliable for professional vetting?

From my experience in talent acquisition, relying solely on AI detectors is a massive gamble. These tools are notoriously prone to false positives, especially with non-native English speakers or highly technical specialists. In my field, we prioritize integrity, but an AI detector doesn't measure character; it measures linguistic patterns. If a candidate uses a template to ensure their resume is "ATS-friendly," a detector might flag that as machine-generated. We should be using these tools as a secondary "red flag" indicator at most, but never as a primary filter for disqualification. The risk of a "Type I" error—rejecting a qualified human—is just too high right now.
Cynthia, if we aren't using detectors, how are we supposed to handle the sheer volume of applications? If 90% of a 500-person pool is using AI to ghostwrite their experience, isn't the entire merit-based system at risk anyway?
I think these tools are dangerous for HR. They lack the nuance to distinguish between a "boring" human writer and a standard AI output.
I agree, Melissa. In fact, some studies show that "highly structured" writing—the kind taught in business schools—triggers detectors more often. We might literally be filtering out the most "professional" candidates by using these.
Justin, the solution isn't better detection, but better assessment design. In the Cyber Security domain, we are moving toward "live" technical challenges and face-to-face logic tests. If a candidate can solve a complex encryption problem in real-time, it doesn't matter if an AI helped them polish their initial cover letter. We have to adapt our interviewing style to test for human critical thinking rather than just scanning text for "originality," which is becoming a very blurry concept in the digital age.
