Can employers tell a resume was written by AI?

Often, yes. Not because of detection software, but because AI-drafted resumes read alike, and a recruiter who has seen four hundred of them this week recognizes the fifth in a sentence. The fix isn’t to avoid AI. It’s to make sure the resume that leaves your hands is specific enough to be only yours.

What recruiters are saying

• The New York Times, reporting on the surge of AI-assisted applications in 2025, found recruiters saying “many of the resumes look suspiciously similar.” ¹
• Greenhouse’s CEO, Daniel Chait, whose software processes applications for thousands of employers: “Everybody’s applications are starting to look more and more alike,” and, “You end up basically not being able to tell anyone apart.” ²
• In a Robert Half survey of more than 2,000 US hiring managers, 67% said reviewing AI-generated applications has slowed the hiring process. ³

Note what’s missing from that list: any claim that a major applicant tracking system flags AI-written text. We looked, and could not find a vendor statement or credible report confirming one. Blog posts asserting that Workday or Greenhouse “detect AI resumes” cite nothing. The screening is human, and it’s about sameness.

What gives an AI resume away

• Filler adjectives and verbs. Seasoned, dynamic, results-oriented, passionate, meticulous, unwavering. Spearheaded, leveraged, utilized, honed. Each is fine once. AI drafts use them in every bullet.
• Claims without numbers. “Drove significant improvements in operational efficiency” is a sentence with nothing in it. AI doesn’t know your numbers, so it writes around them.
• The posting, echoed back. AI tools mirror the job description’s phrasing wholesale, so twenty applicants end up with the same summary paragraph. Keyword matching works; copying the posting doesn’t.
• A summary that could be anyone’s. “Results-driven professional with a proven track record of delivering impactful solutions in fast-paced environments.” Recruiters have read that exact sentence hundreds of times this year.
• Perfect uniformity. Every bullet the same length, the same rhythm, the same structure. Real work history is lumpy.

What the people who hire actually advise

• Greenhouse, in the guidelines for its own hiring process, calls using AI to draft a resume “standard practice,” and asks that what you submit be “your own synthesis, decisions and point of view, not unedited AI output.” ⁴
• Harvard’s career center tells students that generative AI “should not be the primary author,” because “its output will likely be very generic.” ⁵

How to use AI without sounding like it

• Write the facts first, yourself. For each job: what you did, for whom, at what scale, and what changed. Numbers included. Give AI that list, not a job description.
• Use it as an editor, not an author. “Make this bullet shorter” and “start this with a stronger verb” are good uses. “Write me a resume for this posting” produces the generic document everyone else is sending.
• Strip the filler. Delete every adjective that doesn’t carry information. Replace leveraged, utilized and spearheaded with the plain verb: used, built, led, ran.
• Keep one sentence that only you could write. A specific product, a named client, an odd number. That is what a reader remembers.
• Read it aloud. If a sentence sounds like something you would never say, it’s the AI talking.
