Common ATS Resume Mistakes That Stop Candidates From Getting Interviews

What Is an ATS and Why Does It Matter?

An Applicant Tracking System (ATS) is software used by recruiters and HR departments to collect, scan, and sort resumes based on specific criteria before human eyes ever review them. ATS software scans resumes for keywords, formatting, and data consistency to rank candidates.

Because ATS technology filters out resumes that don’t match specific parameters, it’s essential to optimize your resume to make it past this digital screening process. If your resume contains common mistakes that confuse or fail the ATS, your application might be discarded before anyone has a chance to evaluate your qualifications.

Common ATS Resume Mistakes Stop Candidates From Getting Interviews

1. Using Complex Formatting and Graphics

Many candidates believe that unique formatting and creative graphics make their resumes stand out — but ATS systems often can’t interpret these elements.

• Problem: Tables, text boxes, columns, images, and non-standard fonts can cause parsing errors, where vital information is missed or scrambled.
• How to Fix: Use simple, clean formatting with standard fonts like Arial, Times New Roman, or Calibri. Avoid images, graphics, and multi-column layouts. Stick to reverse-chronological or hybrid resume formats which are ATS-friendly.

2. Incorrect or Missing Keywords

ATS scans resumes for keywords relevant to the job description such as skills, certifications, job titles, and industry-specific terms.

• Problem: If your resume misses critical keywords or uses synonyms that ATS may not recognize, your resume may be ranked low or rejected.
• How to Fix: Tailor your resume for each job application by mirroring important keywords exactly as they appear in the job description. Use tools like CV Owl’s guide on creating an ATS-friendly resume to optimize keywords effectively.

3. Using Headers and Footers

Many candidates place their contact information and other details in headers or footers.

• Problem: Most ATS software cannot read text in headers and footers, which means your name and contact info might be missed entirely.
• How to Fix: Place your contact details at the top of the document, outside any headers or footers, in plain text.

4. Submitting Resumes in the Wrong File Format

File format can strongly impact ATS readability.

• Problem: Uploading PDF files or uncommon formats that ATS systems aren’t programmed to parse can lead to lost information.
• How to Fix: Use the file format requested in the job posting. When in doubt, a .docx (Microsoft Word) format is usually ATS-safe.

5. Overuse or Underuse of Keywords

Keyword stuffing—overloading resumes with keywords—can backfire by reducing readability and possibly triggering ATS anti-spam filters. Conversely, too few keywords make your resume irrelevant.

• Problem: Keyword stuffing looks unnatural and may reduce your resume’s chance of ranking well. Sparse use results in poor keyword matching.
• How to Fix: Use keywords naturally throughout your resume, especially in the professional summary, skills section, and job descriptions. Strike a balance to pass ATS and appeal to recruiters.

6. Including Uncommon or Fancy Job Titles

Some companies use creative job titles internally that do not match standard industry terms.

• Problem: ATS filters by common job titles; unusual titles may cause your resume to be overlooked.
• How to Fix: Use both the official job title and the common industry equivalent in parentheses to ensure ATS compatibility.

7. Failing to Use Standard Section Headings

ATS relies on recognized section labels like “Work Experience,” “Education,” and “Skills”.

• Problem: Using unconventional headings like “Where I’ve Worked” or “My Learning Journey” can cause ATS to misread or skip sections.
• How to Fix: Stick to standard resume section headers that ATS algorithms are programmed to identify.

8. Omitting a Skills Section

Many ATS parse resumes by scanning for specific skill lists.

• Problem: Without a dedicated skills section, relevant keywords may be buried or missed.
• How to Fix: Include a clearly labeled “Skills” section listing job-specific hard and soft skills to boost keyword matching.

9. Neglecting to Use Bullet Points for Job Duties

Paragraphs are harder for ATS and human readers to scan quickly.

• Problem: Dense text blocks may cause ATS to misread your achievements or responsibilities.
• How to Fix: Use bullet points to list key duties and accomplishments clearly. This also enhances human readability.

10. Including Irrelevant or Excessive Personal Information

While human recruiters can filter relevant from irrelevant data, ATS might get confused by excessive personal details.

• Problem: Including photos, marital status, hobbies, or unrelated data can clutter your resume and decrease ATS compatibility.
• How to Fix: Keep resumes professional and relevant, focusing on qualifications, skills, and experience only.

How to Ensure Your Resume Passes the ATS

To maximize your chances of getting shortlisted, consider these best practices beyond fixing common mistakes:

• Use Plain Text and Simple Layouts: Stick to classic resume templates that use clear fonts and standard formatting.
• Match Job Description Keywords: Carefully read the listing and mirror the keywords exactly in your resume, especially for skills and qualifications.
• Choose Appropriate File Formats: Always submit files in the format requested by the employer, preferably .docx or ATS-compliant PDFs.
• Keep Contact Details Prominent: Include your name, phone number, email, and LinkedIn URL in the main body, not header/footer.
• Test Your Resume: Use free online ATS resume scanners to identify parsing errors and keyword gaps before applying.
