What Is an ATS? How Applicant Tracking Systems Work in 2026

An applicant tracking system (ATS) is the software a company uses to run hiring: it publishes the job, collects applications, stores each candidate's resume and answers, and tracks every candidate from application to offer. Almost every large employer uses one. In its 2026 review of Fortune 500 careers pages, Jobscan detected an ATS for 97.4% of the companies.

LANDTHATROLE reads job postings straight from these systems: about 28,800 employer job boards on 24 hiring systems, from startups to banks (the full list is on our ATS sources page). This guide explains what an ATS does, what it does and doesn't do with your resume, and how to apply with that in mind.

What an ATS Actually Does

When a company decides to hire, a recruiter opens a job in the ATS, often called a requisition or "req". From then on the ATS handles:

• Job posting: it publishes the listing on the employer's careers page. Systems such as Greenhouse, Lever and Ashby also publish each employer's open jobs as a public job board, which is how LANDTHATROLE can list jobs straight from the source. Employers can also send postings to job boards such as LinkedIn and Indeed.
• Application intake: it receives your resume and form answers. Most systems parse the resume, pulling your name, contact details, work history, education and skills into fields on a candidate profile.
• Search and review: recruiters sort, filter and search the applicant list. In Greenhouse, for example, recruiters can search resumes for keywords.
• Screening questions: employers add questions such as work authorization or location, and can set rules that reject applicants automatically based on the answer.
• Workflow: recruiters move candidates through stages (applied, phone screen, interviews, offer, hired or rejected). Interview feedback, notes and emails are stored in one place.
• Reporting and compliance: it keeps hiring records and reports, such as voluntary equal employment opportunity (EEO) survey answers for US jobs.

The Major ATS Platforms in 2026

A handful of systems cover most jobs, and knowing which one an employer uses tells you what the application will look like. The employers named below are ones whose public job boards we read.

• Workday: part of a larger HR system and the most common ATS in the Fortune 500. Jobscan's 2026 report found that over 40% of Fortune 500 companies use Workday for hiring. Capital One, Salesforce, TD and BMO post jobs on Workday. Its applications usually offer to fill in your work history and education from your resume, which you then check and edit.
• SAP SuccessFactors: another HR suite with a built-in ATS, used by 12% of Fortune 500 companies in Jobscan's 2026 report.
• Greenhouse: widely used by tech companies. Airbnb, Figma and Stripe post jobs on Greenhouse. Its application form accepts PDF, DOC, DOCX, TXT and RTF files.
• Lever: used by companies such as Palantir and Spotify. Lever forms often ask for your LinkedIn profile, so make sure it matches your resume.
• Ashby: a newer system used by many startups. OpenAI, Notion and Ramp post jobs on Ashby.
• iCIMS and SmartRecruiters: systems used by large employers in many industries. Walmart posts jobs on SmartRecruiters.
• Oracle: Oracle Recruiting is part of Oracle's cloud HR software; JPMorgan Chase, Dell and Texas Instruments post jobs on it. Oracle also sells Taleo, an older system whose use among Fortune 500 companies is declining, according to Jobscan.

How ATS Resume Screening Works: What Job Seekers Need to Know

You have probably read that "75% of resumes are rejected by an ATS before a human sees them." There is no study behind that number. Researchers at Mount Royal University and the University of Calgary, writing in The Conversation in July 2026, traced it to a 2012 sales pitch by Preptel, a resume optimization company that went out of business the following year. No methodology was ever published.

Here is what the major vendors actually document:

1. Parsing: the ATS reads your file and fills in a candidate profile. When parsing goes wrong, fields end up empty or wrong. Greenhouse's support page on unsuccessful resume parses lists causes such as graphics, tables, columns, text boxes, and contact details placed in headers or footers.
2. Knockout questions: employers can reject applicants automatically based on their answers to screening questions. Greenhouse calls this auto-reject. Workday lets employers advance or decline candidates automatically with rules, for example declining people who aren't eligible to work in the job's country.
3. Search and filters: recruiters search and filter applicants by keywords, location and other fields. A resume that describes a skill in different words than the posting can be missed in a search, even though nothing rejected it.
4. AI matching, at some employers: newer features compare resumes with the job's requirements. Greenhouse Talent Matching sorts applicants into Strong, Good, Partial or Limited Match, and Greenhouse says it never advances or rejects anyone automatically. Ashby's AI-assisted review marks whether each resume meets each criterion the employer writes. Workday's HiredScore prioritizes candidates by comparing resumes with job requirements. Whether these features are switched on, and how much recruiters rely on them, is up to each employer.

The stricter filter is often the employer's own list of requirements. In the 2021 Harvard Business School and Accenture report Hidden Workers: Untapped Talent, which surveyed more than 2,250 executives in the US, UK and Germany, 88% of employers agreed that qualified high-skills candidates are vetted out because they don't match the exact criteria in the job description. For middle-skills roles the figure was 94%.

If you apply in Ontario, check the posting itself: since January 1, 2026, employers with 25 or more employees must say in a public job posting if they use artificial intelligence to screen, assess or select applicants, under the province's Employment Standards Act rules.

What to Do Differently When Applying Through an ATS

1. Answer screening questions carefully and truthfully. They are where software can reject an application automatically. A wrong click on work authorization, sponsorship or location can end it.
2. Use the posting's words for skills you actually have. If the job says "Kubernetes", write "Kubernetes", not only "container orchestration". Recruiters search for terms like these, and matching tools compare your resume with the listed requirements.
3. Keep the layout simple. One column, standard headings (Experience, Education, Skills), contact details in the body of the page, no graphics. Parsers differ, and you usually don't know which one an employer runs.
4. Check the autofilled form. Workday and other systems fill in the application from your resume. Review every field, especially job titles and dates, before you submit.
5. Apply on the employer's own site. That's where the ATS is. Every job on LANDTHATROLE links to the employer's own application page.

Why Job Listings Straight From the ATS Stay Current

When an employer fills or cancels a job, it closes the requisition, and the posting usually comes off its careers page. Copies of that posting on other websites can stay up after that. LANDTHATROLE lists only jobs on employers' own boards and checks each board again every day. When the employer closes a job, it closes here too, and we don't copy listings from other job boards.

Frequently Asked Questions

Does every company use an ATS?

No. Large employers almost all do: Jobscan detected an ATS for 97.4% of Fortune 500 companies in 2026. Small businesses are much less likely to use one. Researchers writing in The Conversation (2026) note that they often lack the number of applications that makes an ATS worthwhile.

Can you tell which ATS a company uses before applying?

Often, from the application page's web address: boards.greenhouse.io or job-boards.greenhouse.io (Greenhouse), jobs.lever.co (Lever), jobs.ashbyhq.com (Ashby), myworkdayjobs.com (Workday), oraclecloud.com (Oracle Recruiting) and taleo.net (Taleo). Some employers show the ATS form on their own careers domain instead; "gh_jid" in the address is a sign of Greenhouse.

What is an ATS requisition?

A requisition (req) is the ATS record for one open job. It usually holds the job description, the hiring team, approvals and often the budgeted pay range, and the public job posting is created from it. When the job is filled or cancelled, the req is closed and the posting normally comes down.

Does submitting through an ATS mean my application was actually reviewed?

Not necessarily. The automatic rejections vendors document are rules the employer sets up, usually tied to screening questions such as work authorization. Otherwise your application sits in a list that recruiters sort, search and filter, sometimes with AI match ratings. Whether a person reads every application depends on the employer and the number of applicants. Careful answers to screening questions and the posting's own terms for your skills make your application easier to find and assess.
