What an ATS does with your resume

An ATS helps employers manage applications. Resume parsing extracts information into fields such as names, employment history, and contact details. Employers can then use their configured processes to search, review, and move applicants through hiring stages.

Parsing is not the same as a hiring decision. Greenhouse’s support documentation says an unsuccessfully parsed resume can remain attached to a candidate record, with details entered or corrected manually. Roche explains that it uses parsed information to help complete applications and support searches, while its recruiters and managers review applicants and attached CVs.

That is why claims that a fixed percentage of all resumes are automatically rejected by “the ATS” are not a sound basis for editing your document. Systems, employer configurations, eligibility questions, and review processes differ. Concentrate on what you can verify.

An ATS resume checklist, in the order to use it

1. Read the application requirements first

Check the accepted file type and size, required documents, job location, qualifications, and application questions. A polished resume cannot replace a required license or make an inaccurate eligibility answer acceptable. If the instructions request a particular format, use it.

Save a master resume containing your accurate history, then make a role-specific copy. Keep a record of the version you submit so you can discuss the same experience in an interview.

2. Use a simple, consistent structure

A conventional single-column document is a practical starting point. Use recognizable headings such as Experience, Education, and Skills, and show employer names, job titles, and dates consistently. Keep your name and contact information in the document body rather than placing essential details inside decorative objects.

Greenhouse identifies columns, graphics, complex tables, headers, footers, text boxes, and unclear sections as possible causes of parsing problems. These are risks to reduce, not proof that every resume containing one will fail. A plain design still needs useful content and enough spacing to read comfortably.

For each role, make the relationship between title, organization, dates, and bullets obvious. If you held multiple positions at one employer, use clear subheadings and dates rather than compressing everything into a layout that requires visual inference.

3. Choose a supported text-based file

Use the employer’s requested file type. If it accepts both PDF and DOCX, either may be suitable, depending on the document and system. Do not assume that every PDF is readable: a scan or image saved as a PDF can still lack usable text.

Lever’s parsing guidance lists Word and PDF among supported formats and suggests checking whether you can highlight the document’s text. That is a useful first check, not a complete validation of every field or reading order. Keep the file within the application’s stated size limit.

4. Translate the posting into an evidence checklist

Read the responsibilities and required qualifications, then list the relevant skills, tools, certifications, and experience you actually have. Match each one to evidence from work, education, or projects. If a requirement is missing, leave it missing rather than copying it into your resume.

Roche’s guidance explains that recruiters may search for skills and qualifications, and that keywords need context. Use the terminology from the posting when it accurately describes your experience. For an acronym, writing the full term once alongside the abbreviation can help a reader understand it.

Do not add a block of repeated keywords, invisible text, or instructions aimed at an AI system. Those additions do not explain your qualifications and can make the document misleading. See our guide to technical skills on a resume for help choosing relevant skills to describe.

5. Write evidence, not a list of claims

A skill in a list tells the reader what you say you know. A clear experience bullet shows what you did with it. Describe the action, context, and result where you can support the result. You do not need to invent a percentage to make a bullet useful.

If you are changing careers, explain transferable work in terms the new role uses, while keeping your actual titles and employment history truthful. A short resume summary can establish that connection; it should not claim experience you have not had.

6. Check the exported document and application fields

Review the file you will upload, not just the editor. Open it on another screen if possible, select and copy its text into a plain-text document, and read the sequence. Check that names, dates, headings, and bullet text remain intelligible. This catches some extraction problems; it does not reproduce the employer’s parser.

After upload, inspect every field the application fills for you. Correct missing or misplaced details, especially job titles, dates, contact information, and education. Do not assume that an attractive preview means the form is accurate.

Worked example: turn a job requirement into a truthful resume bullet

Illustrative scenario: a fictional operations analyst is applying for a role that asks for Excel reporting, inventory reconciliation, and collaboration with warehouse teams. This example is an editing exercise, not a customer result or an ATS score test.

Job requirement	Evidence the candidate actually has	Where it belongs
Excel reporting	Built a weekly spreadsheet using pivot tables	Skills section and the relevant experience bullet
Inventory reconciliation	Compared stock counts with order records and investigated differences	Experience, with the task explained
Cross-team communication	Reviewed discrepancies with warehouse supervisors	The same bullet or a separate concrete example
SQL	No SQL experience	Do not add it as a skill; assess whether the role requires it

Before: “Responsible for reports and helping the team with stock.”

After: “Built weekly inventory reports in Excel using pivot tables, reconciled stock counts against order records, and reviewed discrepancies with warehouse supervisors.”

The revised bullet names the tool, work, and collaborators. It avoids an invented performance improvement. If the real candidate can verify a result, they can add it; if not, the specific work is still more informative than the original sentence.

What this does not fix: the fictional candidate still lacks SQL. Repeating the word would not create that qualification. Decide whether the role allows learning it on the job or whether another vacancy is a better fit.

A manual parsing check you can do before submitting

1. Open the final file. Confirm that it is the right version and that no comments, placeholders, or tracked edits remain.
2. Select a heading and bullet. Make sure the text is selectable rather than part of an image.
3. Copy all text into a plain-text editor. Read it from top to bottom. Look for interleaved columns, detached dates, missing contact details, or scrambled characters.
4. Check one work-history entry carefully. The title, employer, and dates should be understandable together.
5. Compare it with the posting. Relevant qualifications should be visible and supported, not only implied.
6. Inspect the application after upload. Correct the actual fields and follow any platform-specific instructions.

If the text check fails, simplify the layout or export from the original editable document again. If the file looks correct but the application misreads it, correct the fields rather than repeatedly changing accurate content to chase a score. Keep a copy of what you submitted.

Common issues and what to check next

What you notice	Possible explanation	Useful next step
Text cannot be selected	The file may be a scan or image	Export a text-based version from the original document
Dates appear beside the wrong job	Layout or extraction order may be ambiguous	Use a consistent entry layout and verify the application fields
Contact information disappears	It may be in a header, footer, or object	Move essential information into the document body
A checker says a skill is missing	The phrase may differ, or the skill may genuinely be absent	Add accurate terminology and evidence only if you have the skill
The upload is rejected	The file may not meet the application’s format or size requirements	Read the displayed requirements and export accordingly
Applications receive no response	There may be many causes beyond parsing	Review fit, vacancy status, application completeness, and your overall search process

Questions about ATS resume optimization

What ATS score do I need to pass?

There is no universal passing score across employers. A third-party checker evaluates a document using its own method. Focus on the job’s requirements, accurate information, readable formatting, and the actual application fields.

Is PDF or Word better for ATS?

Use the format the employer requests. When both are allowed, use a text-based file that retains a clear reading order and check the uploaded result. Neither extension guarantees perfect parsing in every system.

Can a two-column resume be read by an ATS?

Some systems can handle it, but columns can create extraction-order problems. A conventional single-column version reduces that risk. Check whether the final text and application fields remain in the correct order.

Should I copy every keyword from the job description?

No. Include the terms that accurately describe your qualifications and show them in context. Do not add skills, certifications, titles, or experience you do not have.

Does my resume have to be one page?

Page count alone is not a universal ATS rule. Use enough space to present relevant experience clearly while respecting the application’s instructions. Our guide to resume length covers the editorial choices in more detail.

Should I tailor my resume for every application?

Review each role and adjust the emphasis where it makes a meaningful difference. You can reuse accurate core history, but different roles may call for different skills and examples. Never change facts simply to resemble a posting.
