AI-Polished Resumes Break ATS Filters, Reshape HR Tech

The resume's value as a hiring signal is eroding. Over 70% of white-collar candidates now use AI to draft their CVs, according to data from Hunar.AI. Among Gen Z, the figure exceeds 85%. When every resume is keyword-optimised to the same standard, recruiters can no longer distinguish strong candidates from polished ones. The consequence is structural: HR technology vendors that depend on resume-based screening face obsolescence, while assessment and interview-first platforms capture rising demand.

## The Signal Collapse: ATS Filters Lose Their Edge

The applicant tracking system (ATS) filter was built to rank candidates on keyword density and formatting. AI resume tools have turned those advantages into baseline expectations. Vinay Jain, co-founder of NexxaScreen, reports that candidates with ATS-optimised resumes now receive 5x to 10x higher shortlist visibility than before, even when holding the same underlying experience. Application volumes surge. The ratio of qualified candidates to total applicants in the top of the funnel drops.

Keyword Optimisation Becomes a Zero-Sum Game

When all resumes tick the same keyword boxes, the ATS cannot rank candidates by actual fit. Krishna Khandelwal, founder and CEO of Hunar.AI, describes the result: “when everyone’s resume is polished to the same standard, recruiters are scanning identical templates.” The resume loses its differentiating power. Recruiters respond by looking for gaps between the polished profile and live conversation.

Recruiters See Through the Template

“Since candidates upload resumes before entering interview rounds, we often notice a gap between how strong a profile appears on paper and how a candidate performs in conversation,” Jain notes. Recruiters are spotting templated language more often. Spotting it does not solve the fundamental problem: the resume no longer carries reliable information about ability. The market for resume-parsing ATS products becomes commoditised.

## The HR Technology Split: Assessment Platforms vs. ATS Commodity

The structural change creates a natural wedge in the HR technology market. Vendors built on resume parsing face margin compression. Platforms offering AI-led interviews, situational assessments, and skills-based evaluations see rising demand.

NexxaScreen and HirePro: Scaling Interview-First Workflows

HirePro, an assessment platform, reports an increase in flagged suspicious behaviour during online tests: from 32.4% of candidates in 2021 to nearly 45% in 2025. The rise in bad-faith applications forces employers to invest in proctored, interactive evaluations. Pasupathi S, HirePro’s chief operating officer, says the real challenge is “separating signal from noise, identifying candidates who possess genuine capability, adaptability, and long-term potential.”

NexxaScreen sends its AI interview to 70 or 80 candidates who cleared the paper shortlist. Jain notes that “several strong candidates are sitting in that rejected pool because their resume did not survive the first filter.” For HR tech buyers, investing earlier in assessment technology reduces the cost of false negatives.

LinkedIn research shows 74% of recruiters struggle to find qualified candidates even as hiring activity runs 40% above pre-pandemic levels. Among recruiters who say hiring has become more difficult, 53% point to a surge in AI-generated applications, while 47% cite shortages of in-demand skills. Hiring teams lean harder on referrals, previous company brands, and portfolio reviews. Professional networking platforms and skills-assessment tools capture more of the hiring value chain at the expense of resume databases.
