You've probably seen the universal applicant tracking system (ATS) resume advice. Single-column layout. Standard section headings. Mirror the keywords from the job posting. That advice isn't wrong — most of it is worth following. But it's aimed at one problem: making sure your resume can be read and stored correctly. It doesn't explain how recruiters actually find candidates once they're in the system. And what happens after that varies significantly depending on which system you're in.
Most ATS guides treat the universal baseline as the whole answer. It isn't. It's the floor. What gets you to the top of the ranked list — what makes a recruiter find you and move you forward — is platform-specific. Workday's recruiter search runs against structured skills fields, not your uploaded document. Taleo's primary filter is a prescreening questionnaire, not keyword density. Greenhouse has no automated scoring at all. The right preparation for each of those systems looks different, and generic advice doesn't capture any of it.
This guide gives you two things: the universal baseline that holds on every platform, and a clear path to platform-specific preparation once you know what you're dealing with.
Try to Find Out First
Before you default to the generic approach, spend two minutes trying to identify the platform. Most of the time, the answer is in the URL.
When you click through to the employer's application page, look at the address bar. Greenhouse applications live at boards.greenhouse.io/{company}. Lever applications live at jobs.lever.co/{company}. Workday URLs contain myworkdayjobs.com. Taleo URLs contain taleo.net. If the URL doesn't tell you, click Apply and watch where the redirect goes — many custom career pages redirect to the ATS's native domain as soon as you start an application.
For a full walkthrough of how to identify the platform — including what to do when the URL is a custom domain and how to read the page source — see How to Find Out Which ATS a Company Uses. If you can identify the platform, go there first. The rest of this guide is for when you genuinely can't.
The Universal Baseline
These are the practices that consistently help regardless of which ATS you're using. They won't optimize you for every platform's specific ranking mechanism, but they form a reliable baseline everywhere.
Formatting
- Single-column layout throughout. Multi-column layouts increase the risk of parsing errors across every major ATS platform — content interleaves, work history scrambles, skills disappear.
- Contact information in the document body, not a header or footer. Many resume parsers handle headers and footers inconsistently — body content is more reliably extracted across every major platform. Your name and contact details need to be in the main text.
- No image-based content. Any text that exists as part of an image — a graphical header, a visual skill chart, a styled banner — won't be extracted. To the parser, it doesn't exist.
- Standard section headings: Work Experience, Education, Skills, Certifications. Non-standard headings cause sections to be misfiled or dropped.
- Save as .docx or text-based PDF. Test the PDF by trying to select and copy the text — if you can't, it's image-based and won't parse correctly on any platform.
The plain text test. Paste your entire resume into Notepad or any plain text editor. This isn't identical to how ATS parsers work, but it's a useful approximation. Content that disappears or becomes unreadable in plain text often creates parsing problems as well. If your work history reads cleanly and in order, the formatting is likely sound.
Keywords and skills
- Include a dedicated, clearly labeled Skills section. Skills buried only in prose extract less reliably than skills in a labeled section across every platform that uses tag-based indexing.
- Key qualifications should appear in both your Skills section and naturally within experience bullets. Neither location alone is optimal — the Skills section produces reliable tag extraction; the experience bullets provide context and density.
- Include both full form and abbreviation for every credential, tool, or methodology where either form might be searched. "Project Management Professional (PMP)" rather than just one or the other. This matters on Lever, where abbreviations and spelled-out forms are treated as different strings, but it's a safe practice everywhere.
Application questions
- Read every screening question carefully before answering. Some are configured as automatic disqualifiers — a wrong answer closes the application before a recruiter sees it. They don't look different from standard questions. Treat every minimum-qualification question as potentially consequential.

The Job Description Is Your Cheat Sheet
This is the part of the universal approach that most guides understate.
Every ATS platform — regardless of its scoring mechanism — runs on the vocabulary of the job description. Workday's skills fields are populated with terms drawn from the posting. Taleo's prescreening questions are built from the required and preferred qualifications listed in the job description. Greenhouse's scorecard attributes trace directly back to the posting's requirements section. iCIMS's tag index scores you against the terms the recruiter used when configuring the role. Lever's recruiters search using the language they put in the posting.
The mechanisms differ entirely. The input is the same.
If you only have time to tailor one thing, tailor the language of your resume to the language of the posting.
When you don't know which platform you're dealing with, the job description becomes more important, not less. You can't optimize for a specific system's quirks. You can optimize for the vocabulary the hiring team used to define the role — and that vocabulary is right in front of you.
What this means in practice:
- Read the requirements section carefully. Not to extract a keyword list, but to understand which qualifications are actually driving the hiring decision. Requirements listed early and in multiple sections tend to be weighted more heavily. Ownership language — "lead," "own," "define" — signals a different role than "support" or "assist," even at the same title level.
- Use the posting's exact terms. Where the posting says "stakeholder management," your resume should say "stakeholder management" — not "cross-functional communication" or "relationship building," even if those describe the same work. Near-synonyms fail on exact-match systems. Exact vocabulary works everywhere.
- Include both forms of every abbreviated term. If the posting uses "CI/CD," include "Continuous Integration/Continuous Deployment (CI/CD)." If it uses the full form, include the abbreviation in parentheses. You don't know which form the recruiter will search for.
- Check that key qualifications are evidenced, not just mentioned. A bullet that lists "stakeholder management" as a skill gives a reviewer a keyword. A bullet that describes coordinating six business units through a system migration gives them evidence. Evidence holds up on every platform; mentions are the minimum.

Knockout Questions
Most ATS platforms allow employers to configure screening questions that automatically disqualify candidates before a recruiter reviews the application. The questions aren't labeled as disqualifiers — they look identical to standard application questions. A wrong answer removes your application from the active pool immediately.
Common disqualification criteria include work authorization, minimum education level, required certifications, and non-negotiable conditions like relocation or shift availability. The advice is the same regardless of platform: read every question before answering, and answer accurately. If you don't meet a stated requirement, the application isn't the right place to work around it.
The specific mechanics vary by platform — Taleo's tiering system, Workday's silent auto-disqualification, SAP SuccessFactors' score-based threshold. Once you've identified the platform, the relevant guide covers how that system handles screening questions specifically.
The Baseline Gets You In. Platform Knowledge Gets You to the Top.
Everything above ensures you don't fail on any platform. It doesn't ensure you rank well on any specific one.
The platforms that matter most for high-volume enterprise hiring each have a mechanism that determines review priority — and that mechanism isn't covered by the universal baseline.
Workday recruiters search against structured profile fields, not your uploaded resume. A resume that parses cleanly but leaves the skills fields incomplete is invisible to recruiter search. Verifying your skills fields after upload — and populating them with the exact language of the posting — is the difference between being in the database and being findable in it.

Taleo sorts every applicant into one of three review tiers based on prescreening responses, before a recruiter looks at any resume. A keyword-perfect resume with thin prescreening answers lands in the second tier. The candidates in the first tier answered the Asset criteria — the preferred qualifications — as thoroughly as the Required ones. Read the Taleo guide →
Greenhouse has no automated scoring gate. A human reviewer often evaluates candidates against a structured scorecard built from the job description. The question isn't whether the right keywords appear — it's whether your resume demonstrates specific evidence for each competency the role requires. Mentions don't move you forward. Evidence does. Read the Greenhouse guide →
Lever indexes the full text of your resume and relies on human review rather than algorithmic filtering. The platform doesn't expand abbreviations — a recruiter searching "Search Engine Optimization" won't find a resume that only says "SEO." The abbreviation gap is the most common way qualified candidates become invisible in Lever. Read the Lever guide →
iCIMS uses three mechanisms simultaneously: a skills tag index, full-text Boolean search, and an AI scoring layer that reads only the parsed profile — not your uploaded document. A formatting problem doesn't just make you harder to find; it means the AI score the recruiter sees was calculated from inaccurate data. Read the iCIMS guide →
SAP SuccessFactors has a file format preference most candidates get wrong. SAP's own documentation lists DOCX as the supported parsing format — PDF is not in the primary list, and image-based PDFs are explicitly problematic. For a platform where the parsed profile is heavily integrated into the candidate record recruiters review, a format choice that degrades the parse has compounding consequences. Read the SAP SuccessFactors guide →
The universal baseline is worth doing regardless of platform. But the baseline only prevents avoidable mistakes. Once you've handled the basics, the biggest gains come from understanding the system you're actually applying through. That's what separates a resume that's in the database from one that gets found, scored correctly, and moved forward.
