How recruiters actually use an applicant tracking system (ATS): the data
Job seekers hear that "the ATS robot" rejects most resumes. The published data tells a more useful story: recruiters search and filter a growing pile of applications with keywords and rules they choose. This page collects the best current numbers, with every source linked, and explains what they mean for your resume.
Key findings
- Nearly all large employers use an ATS: Jobscan detected one at 97.4% of Fortune 500 companies in 2026.
- 99.7% of recruiters surveyed use ATS filters, and 76.4% filter by skills first.
- Applications per job at Greenhouse customers rose from 116 in 2022 to 244 in 2025, while recruiters per company fell 56%.
- Documented auto-rejection comes from rules recruiters set (for example, knock-out questions), not from a hidden score of your resume's design.
- The famous "75% of resumes are rejected by ATS" claim has no published study behind it.
Who uses an applicant tracking system
For anyone applying to a mid-size or large company, assume an ATS stores and indexes your application. Jobscan's earlier editions of the same Fortune 500 study put the share at 98–99%; the exact figure moves a little each year, but the answer is "nearly all".
Which applicant tracking systems employers use
Market share depends on which companies you count. Among the Fortune 500, two enterprise systems dominate. Across a broader set of 13,130 companies seen by Jobscan's users, the mid-market systems lead.
| ATS | Fortune 500 share (2026) | Share across 13,130 companies |
|---|---|---|
| Workday | Over 40% | 17.5% |
| SAP SuccessFactors | 12% | — |
| Greenhouse | — | 19.0% |
| Lever | — | 15.6% |
| iCIMS | — | 14.4% |
| Oracle Taleo | Falling | — |
All of these systems let recruiters search applicants by keyword and filter by fields and screening answers. The keyword logic, not the brand, is what matters for your resume.
How recruiters filter and search applicants
In a February–March 2025 survey of 384 recruiters by Jobscan, nearly every recruiter said they narrow applicant lists with ATS filters. The most common filters:
| Filter | Share of recruiters |
|---|---|
| Use any ATS filter | 99.7% |
| Skills (filter first) | 76.4% |
| Education | 59.7% |
| Job title as a keyword | 55.3% |
| Certifications | 50.6% |
| Years of experience | 44%+ |
| Location | 43.4% |

Greenhouse describes the same behavior from the vendor side: recruiters "conduct search queries to identify candidates that meet a combination of specific criteria". A skill you have but describe in other words is invisible to that query. That is why resume keywords matter: they are literally the search terms.
Why filtering keeps growing: application volume
Source: Greenhouse, The Hire Standard (6,000+ companies, 640M+ applications), March 2026.
More applications per job and fewer recruiters per company means each recruiter has far less time per application. Greenhouse also reports that applications per job rose 102% from Q3 2022 to Q4 2024, after ChatGPT's release, and that 34% of recruiters spend up to half their week filtering spam and junk applications. When the pile grows, the filter does more of the work.
On the job seeker side, 49% of US job seekers told Greenhouse in late 2025 that they send more applications than a year before. Huntr's 2025 data from its users shows a median of about 16 applications per week, and 18% of users needed more than 100 applications before an offer.
Does the ATS automatically reject resumes?
Usually not on its own. The documented ways an application is rejected without a person reading it are rules that the employer sets:
- Knock-out questions. In Greenhouse, a recruiter can set an auto-reject rule on a yes/no or multiple-choice screening question, such as work authorization or a required license. Answer "no" and the rule rejects the application.
- Hard filters. Employers can filter by degree, years of experience, or employment gaps. Harvard Business School's Hidden Workers study found that 88% of employers believed qualified high-skills candidates were screened out by such criteria, and 94% said the same for middle-skills candidates.
Greenhouse states that its auto-reject feature works only on rules "set by recruiters". For everything else, the practical risk is not a robot saying no — it is a recruiter's search or filter never surfacing your resume among 200+ others.
The "75% of resumes are rejected by ATS" myth
The claim that ATS software rejects 75% of resumes before a human sees them traces back to a 2012 statement by Preptel, a company that sold resume-optimization software. Computerworld and Fortune both attributed the figure to Preptel. No method or data was ever published. Treat any article that repeats it as unsourced.
AI on both sides of hiring
Hidden keywords and AI tricks are not a shortcut. Recruiters are actively looking for them, and the visible result is a resume that looks dishonest. TopResume's 2025 survey of 600 US hiring managers found 19.6% would reject a candidate for an AI-generated resume; more were fine with AI help when the final text reads as the candidate's own.
What this means for your resume
- Write for the search. Use the job post's exact terms for skills, tools, and the job title that are true for you.
- Answer screening questions carefully. They are the most common real auto-reject.
- Lead with skills. Most recruiters filter by skills first; put the required ones in bullets near the top.
- Stay honest. Recruiters now expect AI-assisted resumes and watch for deception. Truthful tailoring wins; keyword stuffing does not.
- Check before you send. Run a free ATS keyword check against the job post.
