ATS-Friendly Resume: Format, Keywords, and Examples

An applicant tracking system, or ATS, is software employers use to collect applications and manage candidates through the hiring process. Many systems can parse resume text into structured fields such as work history, education, skills, job titles, and contact information.

An ATS-friendly resume therefore needs two things at the same time: a structure that software can interpret reasonably well and content that makes your relevant qualifications clear to the people reviewing the application.

There is no single ATS used by every employer, and systems differ in how they parse, search, filter, match, or rank candidate information. That is why universal claims such as one perfect template, one required keyword density, or one guaranteed ATS score should be treated cautiously.

A common ATS workflow starts when your application and resume enter the employer's recruiting system. Resume-parsing technology may extract details from the document and organize them into a candidate profile that recruiters can review or search.

What happens after parsing depends on the employer and the software. Recruiters may search for skills, filter on qualifications, review applications manually, or use matching features that compare candidate information with job requirements.

That distinction matters. A resume can be technically parseable and still be a weak application if the most relevant experience is vague, buried, or missing. Formatting is only one part of ATS readiness.

Simple does not have to mean ugly. A resume can look polished while still using a predictable reading order and clear text hierarchy.

The safest baseline is a document where someone can move from your name and contact information to summary, skills, experience, projects, and education without guessing where each section begins.

• Use one clear primary reading order.
• Use consistent formatting for company names, job titles, dates, and locations.
• Use normal text for essential information rather than turning it into images.
• Keep heading styles consistent from section to section.
• Use bullets for achievements when they improve scanning.
• Leave enough white space to separate sections without creating large decorative gaps.
• Avoid design choices that make the document difficult to understand when read from top to bottom.

Creative headings can make a portfolio feel distinctive, but a resume is usually not the best place to make a reader decode what a section means. Standard labels reduce ambiguity.

• Experience or Professional Experience
• Skills or Technical Skills
• Education
• Projects
• Certifications
• Awards, Publications, or Volunteer Experience when relevant

Complex layout is one of the clearest areas where ATS behavior can differ. Some parsing systems handle sophisticated documents better than others, while others can misread text order or fail to extract information placed in certain design elements.

Greenhouse's own support documentation lists complex tables, headers, footers, text boxes, graphics, photos, word art, and columned layouts among formatting patterns that can contribute to unsuccessful or partial parsing.

That does not mean every two-column resume fails every ATS. It means you should avoid making essential information depend on a layout feature that a parser may interpret differently.

Your name, email address, phone number, location, and relevant professional links should be easy to locate. Avoid relying on an image, decorative icon, header, footer, or text box as the only place where critical contact information appears.

This is especially important because parsing software may use structural patterns to determine which text represents a candidate's name, current role, employer, phone number, or email address.

• Write your email address as text.
• Write your phone number as text.
• Use descriptive text for portfolio, LinkedIn, or GitHub links when appropriate.
• Keep your name visually prominent but still selectable as text.
• Do not use an image of your contact block as a design shortcut.

There is no honest universal answer because application systems and employer settings differ. Major recruiting platforms support multiple resume formats. Greenhouse, for example, accepts DOC, DOCX, PDF, RTF, and TXT for candidate uploads, while Lever also supports common resume file types including DOC, DOCX, PDF, and TXT.

Greenhouse's candidate guidance currently recommends PDF for its own MyGreenhouse workflow, but that should not be turned into a rule for every employer or ATS.

The best decision is simple: follow the file-type instruction in the job application. If the employer explicitly asks for PDF, send PDF. If it asks for DOCX, send DOCX. If either is accepted, use the version that preserves a clean, text-based layout and verify that the exported document still contains selectable text.

Relevant terminology matters because ATS profiles can be searched and some recruiting systems offer matching features based on skills, experience, qualifications, or job requirements.

But copying a list of words from the job description is not the same as demonstrating fit. The stronger approach is to identify the role's important requirements, match them to experience you genuinely have, and use the employer's terminology where it accurately describes that evidence.

A clean format cannot compensate for an unfocused resume. If the job emphasizes customer onboarding, SQL reporting, API reliability, enterprise sales, financial modelling, or another central responsibility, relevant evidence should be easy to find when you actually have it.

Tailoring does not mean changing your history. It means changing emphasis: selecting the most relevant bullets, ordering skills intentionally, clarifying vague wording, and making the connection between the job's priorities and your real experience easier to see.

1. 1

   Identify the job's core requirements

   Separate central responsibilities and must-have qualifications from general company language.

2. 2

   Match each requirement to real evidence

   Find the project, responsibility, result, skill, or credential that supports it.

3. 3

   Move the strongest evidence forward

   Prioritize relevant bullets and skills so the reader does not have to hunt for them.

4. 4

   Use accurate job terminology

   Name tools, methods, certifications, and functions accurately when they describe work you have actually done.

5. 5

   Remove unsupported language

   Do not add qualifications simply because they appear in the posting.

The fictional example below shows why formatting and relevance need to work together. The candidate already has the experience described; the improvement is in how clearly it is presented.

You cannot perfectly simulate every employer's ATS at home, but you can catch obvious document problems before applying.

1. 1

   Confirm the text is selectable

   Open the exported resume and make sure important content is actual text rather than a flattened image.

2. 2

   Copy the text into a plain-text editor

   Check whether the basic reading order is still understandable. This is not an ATS test, but it can reveal obvious ordering problems caused by complex layout.

3. 3

   Review names, titles, companies, and dates

   Make sure each role's core information appears together and is easy to interpret.

4. 4

   Check the target job terminology

   Confirm that important terms appear naturally where they are supported by your background.

5. 5

   Read it as a recruiter

   The document should make sense without knowing why you chose each keyword or formatting decision.

The same resume structure can support very different applications. A software engineer targeting a backend role may need to surface APIs, databases, service reliability, cloud infrastructure, or production ownership, while a frontend role may prioritize TypeScript, UI architecture, accessibility, performance, and design-system work.

The format helps the information travel through the application system. The role-specific evidence gives the information a reason to matter.

• Putting your name or contact information only inside a header, footer, image, or text box.
• Using multiple columns when a simpler reading order would communicate the same information.
• Turning important skills or ratings into charts, icons, progress bars, or graphics.
• Using clever section headings that make the document harder to interpret.
• Uploading an image scan instead of a text-based resume.
• Assuming PDF or DOCX is universally superior instead of following the application instructions.
• Repeating keywords without connecting them to evidence.
• Adding skills, tools, titles, or accomplishments you cannot support.
• Chasing an ATS score while making the resume worse for a recruiter to read.
• Using one generic resume for jobs that prioritize substantially different responsibilities.

• Is the resume built from real selectable text rather than an image?
• Are your name and contact details easy to locate?
• Are Experience, Skills, Education, Projects, and other sections clearly labelled?
• Do roles show recognizable job titles, companies, and dates consistently?
• Can the document be read in a clear top-to-bottom order?
• Have you avoided making critical information depend on graphics, text boxes, headers, footers, or complex columns?
• Are the most important job requirements represented when you genuinely meet them?
• Do important keywords connect to experience, projects, skills, or credentials?
• Did you follow the employer's requested file format?
• Can you defend every important claim in an interview?
• Does the resume still read naturally and persuasively to a person?
