Workday. Taleo. Greenhouse. iCIMS. These companies built the machines that silently filter you out every day.
These Are the Systems Deciding Your Career
Every time you apply to a mid-size or large company, your application goes through one of these systems. Five companies dominate the ATS market.
Workday Recruiting — Market Leader (34%)
Used by 1 in 3 Fortune 500 companies. Its parser is aggressive about format. Anything it can't cleanly read gets stripped out or misread.
Known users: Amazon, Walmart, Bank of America, Accenture, Netflix, Deloitte
What Workday hates: Multi-column layouts, tables, text boxes, embedded images, PDFs from Canva
Oracle Taleo — Enterprise (22%)
Built in 1999, still rejecting people in 2025. Notorious for forcing applicants to re-enter their entire CV into form fields even after uploading it.
Known users: HSBC, Oracle, Procter & Gamble, ExxonMobil, Boeing, Nestle
What Taleo hates: Special characters (e, n, u), non-standard date formats, LinkedIn-generated PDFs, files over 1MB
iCIMS — Common (16%)
Dominant in pharma, logistics, retail. Uses "candidate ranking" — your application is automatically ranked against every other applicant.
Known users: FedEx, L'Oreal, Pfizer, Marriott
What iCIMS hates: Skills-based CV format instead of chronological, employment gaps with no context
Greenhouse — Growing (12%)
The tech-sector favorite. Places higher weight on skills-based matching and less on job title history.
Known users: Airbnb, Dropbox, HubSpot, Slack, Intercom
What Greenhouse hates: Vague accomplishments without metrics, skills listed only in a sidebar
