7 ATS Resume Mistakes That Can Cost You Interviews in 2026
by Patrick Da Costa Guimarais • Last Updated 8/17/2026

You spent hours perfecting your resume. You found the right job, clicked “submit,” and waited for the interview request.
And then… silence.
It is easy to blame a faceless robot. An applicant tracking system (ATS) may be part of the process, but there is no single system or universal rejection rule. Employers configure their hiring software differently. Some use it mainly to collect applications; others search, filter, or compare resumes using job-related terms.
Your goal is not to beat a secret algorithm. It is to submit a resume that the employer’s software can parse and a recruiter can understand quickly.
What Is an Applicant Tracking System (ATS)?
An ATS helps employers collect, organize, and review job applications. Depending on the employer and its setup, the system may extract your contact details and work history, search for specific skills, or help recruiters prioritize applications.
That does not mean every ATS automatically rejects a resume because of one formatting choice. A complicated layout can cause a partial or incorrect parse, and missing job requirements can weaken your application. The seven fixes below reduce those risks without turning your resume into a page of keyword-stuffed text.
What Are the Most Common ATS Resume Mistakes?
1. Ignoring the Requested File Format
The problem: You upload a JPEG, PNG, Pages file, or scanned PDF even though the application asks for a document. The file may look right on your screen while giving the parser little or no selectable text.
The fix: Follow the instructions in the job posting. If the employer accepts both PDF and DOCX, use a clean DOCX or a text-based PDF. Greenhouse, for example, currently accepts DOC, DOCX, PDF, RTF, and TXT candidate uploads. It also lists image-based resumes among the files that may fail to parse correctly. (Greenhouse Support)
After exporting a PDF, try selecting and copying a sentence. If you cannot select the text, the file may be an image rather than a text-based document.
Avoid: YourNameResume.jpeg, YourNameResume.pages, or an image-only PDF
Use: The file type requested by the employer, usually a clean DOCX or text-based PDF
2. Using Columns, Tables, or Text Boxes for the Layout
The problem: A two-column resume can look polished while the extracted text appears in the wrong order. Tables and text boxes may also separate a heading from the experience it describes.
The fix: Use a single-column layout with a clear top-to-bottom reading order. Greenhouse’s parser guidance specifically lists columns, tables, headers, footers, and text boxes as formats that can lead to partial parsing. (Greenhouse Support)
You can still use spacing, bold text, and simple section breaks. Let the structure make your experience easier to scan.
Avoid: Side-by-side experience sections or tables used to position text
Use: One column with consistent headings, dates, and bullet points
3. Putting Contact Information Only in the Header or Footer
The problem: Your name, email, and phone number appear only in the document header. Some parsers may not place that information in the expected candidate fields.
The fix: Put essential contact details at the top of the main document body. Keep them as plain text, and check that your email address and phone number remain readable after you export the file.
Avoid: Contact details that appear only in a header, footer, image, or text box
Use: Your name, location, email, phone number, and relevant profile link in the main body
4. Replacing Standard Section Names With Clever Labels
The problem: “My Professional Journey” may sound more personal than “Work Experience,” but it makes the section less obvious to software and recruiters.
The fix: Use conventional headings for the information an employer expects. Save your personality for your achievements, summary, portfolio, and interview.
Avoid: “My Story,” “Where I Shine,” or “Things I Know”
Use: “Professional Summary,” “Work Experience,” “Skills,” “Education,” and “Certifications”

5. Using Graphics to Carry Important Information
The problem: A logo, skill bar, icon, or chart contains information that does not appear anywhere as text. A parser may skip the graphic, and a recruiter may not know what “four out of five stars” means.
The fix: Write important skills and results in plain text. If you include design elements for a creative role, make sure the resume still makes sense when the text is copied into a plain document.
Avoid: A bar showing “90% Adobe Photoshop” with no written context
Use: “Adobe Photoshop: advanced” or, better, a bullet showing what you produced with it
6. Choosing Style Over Readability
The problem: A script font, tiny type, unusual symbols, or inconsistent date formatting makes the resume harder to read after upload or conversion.
The fix: Choose a familiar, readable font and keep the formatting consistent. Arial, Calibri, Georgia, Garamond, and Times New Roman are reasonable options. A 10–12 point body size works for many resumes, but readability matters more than squeezing everything onto one page.
Font choice alone is unlikely to decide whether you get an interview. Clear job titles, dates, section headings, and achievement bullets matter more.
Avoid: Decorative type, very small text, and symbols that replace words
Use: A readable font, consistent month-and-year dates, and simple round bullet points
7. Copying Keywords Without Showing the Skill
The problem: You send the same generic resume to every role—or paste a block of keywords into the document without evidence that you have those skills.
The fix: Compare your resume with the job description. Use the employer’s wording when it accurately describes your experience, then prove the skill with a project, action, or result. The U.S. Equal Employment Opportunity Commission notes that employers may use hiring technology to screen resumes for keywords or experience, but the exact process varies. (EEOC)
If the listing asks for “customer relationship management” and you used Salesforce to manage 80 accounts, say that. Do not add a skill you cannot defend in an interview.
Avoid: A hidden keyword list or a generic resume for every marketing role
Use: Job-specific language inside accurate, achievement-based bullets
The same rule applies to your cover letter: match the role without copying the posting line for line. LifeShack’s AI cover letter generator can give you a job-specific draft to review and personalize.

Frequently Asked Questions About ATS Resumes
Should an ATS resume be a PDF or DOCX?
Follow the employer’s instructions. If both formats are accepted, a clean DOCX or text-based PDF can work. Check that your PDF text is selectable and that the document still reads correctly when copied into plain text.
Do ATS platforms automatically reject resumes?
Not all of them. An ATS may store applications, extract resume data, search for terms, apply employer-defined filters, or support ranking and review. A formatting problem can cause an incomplete parse, but it does not create one universal automatic-rejection rule.
Can I use a two-column resume in 2026?
You can, but a single column is the safer choice when you do not know which parser an employer uses. If you keep two columns, copy all the text into a plain document and confirm that the reading order still makes sense.
Should I repeat keywords from the job description?
Use important terms when they truthfully describe your work. Put them in context with an action, project, tool, or result. Repetition without evidence makes the resume weaker for the person who eventually reads it.
