Understanding Which ATS Your Application Goes Through
Nearly every large employer runs an Applicant Tracking System, and each system parses a resume differently — formatting that works perfectly in one ATS may break in another. Every ranking and example below comes from our portal-verified State of ATS 2026 dataset (738 large employers checked by hand, 704 verified, re-verified July 2026, open data) — not from vendor marketing.
1. Workday Recruiting — 38.0% of verified large employers
Verified users: Adobe, Bank of America, Boeing, CVS Health, Capital One, AccentureThe single most common ATS among large corporations — but at 38%, far from the "75%" figure often repeated online. It integrates with the company's broader HR suite. Tips: Workday parses standard formats well. Use clear section headings (Experience, Education, Skills). Avoid tables, columns, and graphics. Always fill in all fields in the online application — do not rely solely on your uploaded resume.
2. Greenhouse — 12.6%
Most resumes are screened by an ATS before a human sees them

Greenhouse is the tech industry's favorite and focuses heavily on structured hiring processes. Tips: Greenhouse has solid parsing capabilities. It extracts skills, work history, and education reliably from well-formatted PDFs. Include a skills section with keywords matching the job post.
3. SAP SuccessFactors — 9.6%
Verified users: EY, American Airlines, BMW, Audi, Honda, CapgeminiPopular with multinational corporations, especially in Europe — and growing: our July 2026 re-verification found several large employers had quietly migrated onto it. Tips: Parsing is stricter than modern systems. Keep formatting simple, use standard section headers, and avoid non-standard characters.
4. Oracle Cloud HCM — 6.9%
Verified users: JPMorgan Chase, American Express, Kroger, Hilton, Albertsons, Oracle itselfOracle's modern recruiting cloud (the successor to Taleo) — routinely missing from ATS market-share lists even though it runs hiring at some of the biggest employers in banking and retail. Tips: Handles standard PDFs well. Complete every form field; the structured application data matters as much as the uploaded file.
5. iCIMS — 5.5%
Verified users: Atlassian, Costco, Uber, AMD, Alaska Airlines, AonOne of the largest dedicated ATS providers, popular in retail, healthcare, and manufacturing. Tips: iCIMS supports PDF and Word formats. Use standard headings, avoid headers/footers (they may not parse), and include both spelled-out terms and acronyms (e.g., "Search Engine Optimization (SEO)").
6. Avature — 3.7%
Verified users: Deloitte, IBM, Bloomberg, Bain & Company, CBRE, Ally FinancialA flexible enterprise CRM/ATS that big consulting, finance, and services firms increasingly run as their primary apply flow. Tips: Parsing is solid but portals are heavily customized per company — read each form carefully and fill every required field rather than relying on the parsed resume.
7. Eightfold — 3.4%
Verified users: Microsoft, Netflix, Citigroup, Morgan Stanley, Starbucks, AstraZenecaAn AI-native talent platform that matches your whole profile against the role — not just keywords. Tips: Eightfold reads context, not just keyword counts. A clear career story with concrete skills and outcomes beats keyword stuffing here.
8. SmartRecruiters — 2.7%
Verified users: McDonald's, ServiceNow, AB InBev, AbbVie, AECOM, AccorA modern, user-friendly system common at global consumer and services companies. Tips: Good parsing of PDFs and Word docs. Still, stick to clean formatting for best results.
9. Taleo (Oracle, legacy) — 2.5%
Verified users: UnitedHealth Group, Kaiser Permanente, Hyatt, Cognizant, Jacobs, D.R. HortonThe system career advice still warns about most — but its install base is collapsing: it ranked #6 in our June 2026 audit and fell to #10 by the July re-verification as employers quietly migrated off it. Where it survives, its parsing is the most dated on this list. Tips: Taleo has the most issues with complex formatting. Use a single-column layout, no tables, no images, and standard fonts. See our ATS-friendly format guide.
10. Ashby — 2.1%, and rising fast
Verified users: OpenAI, Snowflake, Notion, Plaid, Ramp, ConfluentThe high-growth tech world's new default — Ashby was the #1 destination in our July 2026 migration tracking, and most frontier AI labs run hiring on it. Tips: Ashby has modern parsing that handles most formats well. It is particularly good at extracting structured data from clean, standard resumes. Worth knowing: several household names run none of the above — about 4% of verified large employers (Apple, Google, Amazon, Meta, LinkedIn, plus federal agencies) use their own internal systems with no third-party parser to optimize for. And Lever, long a startup staple, now runs hiring at under 1% of large employers — several of its biggest logos migrated away in 2026.
