ATS Parsing Errors That Kill Good Applications Before a Human Ever Reads Them

Applicant tracking systems process the majority of job applications at medium and large companies before any human ever sees them. This means a formatting error, an unusual character, or a poorly structured section can eliminate an otherwise perfect application before it reaches a recruiter's desk. Understanding how ATS systems parse resumes — and where they commonly fail — is one of the highest-leverage improvements you can make to your job search.

The Most Common ATS Parsing Errors

ATS platforms extract text from your resume and store it in structured fields: name, contact info, job titles, employers, dates, skills, and education. When your formatting confuses this extraction process, data ends up in the wrong field or disappears entirely. Here are the errors that cause the most damage.

• Headers and footers containing contact information. Many ATS systems cannot read content placed in Word headers or footers. Put your name, email, phone, and LinkedIn URL in the main body of the document.
• Tables and text boxes. Content inside tables or text boxes is frequently skipped entirely. Use simple paragraph and bullet formatting instead.
• Graphics, charts, and icons. Any information embedded in an image — including icon-based skill ratings — is invisible to ATS. Use plain text for all meaningful content.
• Unusual section headings. "Where I've Been" is charming; "Work Experience" is parseable. Stick to standard section names that ATS systems are trained to recognize.
• Two-column layouts. Many ATS systems read left to right across columns rather than top to bottom within each column, scrambling your content. Use a single-column layout for maximum compatibility.
• Non-standard fonts and special characters. Decorative bullets, arrows, and non-Unicode characters can corrupt the parsed text. Use standard bullet points and clean fonts.

How to Test Your Resume for ATS Compatibility

The simplest test is to copy and paste the text of your resume into a plain-text editor like Notepad. What you see is approximately what an ATS will extract. If the text is scrambled, out of order, or missing sections, your resume will not parse correctly. Fix the formatting until the plain-text version is clean and logical.

ApplyGlide builds resumes using ATS-optimized templates by default, ensuring your content is always structured in a way that machines can read and humans find compelling. If you are uploading an existing resume to job portals, run this plain-text test first — it takes two minutes and can fundamentally change your application success rate.

File Format Matters Too

Submit your resume as a .docx or PDF file, but check the job posting first. Some older ATS platforms struggle with PDFs. When in doubt, .docx is the safer choice for automated processing, while PDF preserves your visual formatting for human readers. Many applicants send two versions when both are accepted.
