Most resumes don't fail because the candidate is unqualified. They fail because the text never reaches the recruiter in a readable form, or because the recruiter can't quickly see the required skills. This guide explains the common causes and how to fix each one.
What an applicant tracking system (ATS) does
An applicant tracking system stores applications and helps recruiters sort and search them. Most systems read the text of an uploaded resume and store it in fields such as name, email, job titles, employers, dates, and skills. Recruiters then search or filter those fields. If a field is missing or garbled, the candidate can be harder to find, even if they match the job.
Different systems behave differently, and employers configure them differently. No guide can tell you exactly how a specific company's system scores resumes. What you can control is whether your resume is easy to read and whether it clearly states the skills the job asks for.
The most common problems
- Multi-column layouts. Text in two columns can be read left-to-right across the page, mixing job titles with unrelated bullets.
- Tables and text boxes. Some parsers skip or scramble content inside tables, text boxes, and sidebars.
- Headers and footers. Contact details placed in the page header may not be read at all.
- Graphics, icons, and skill bars. A bar showing "Python: 80%" tells a person little and tells a parser nothing.
- Unusual section names. "Where I've Made an Impact" is harder to categorize than "Experience."
- Scanned or image-based PDFs. If the file is a picture of text, the text may not be extracted at all.
- Missing job-specific terms. If the job description asks for "stakeholder management" and your resume only says "worked with teams," the match is weaker.
A quick checklist
- Use one column, with standard section names: Summary, Experience, Skills, Education.
- Put job titles, employers, and dates on their own lines in plain text.
- Avoid tables, text boxes, icons, photos, and skill bars.
- Keep contact details in the main body, not in the header.
- Export as a text-based PDF or .docx. Check that you can select and copy the text.
- Use the exact wording from the job description for skills you actually have.
- Include the tools, certifications, and technologies by their full names and common abbreviations, such as "Search Engine Optimization (SEO)."
How to test your resume
Copy all the text from your PDF and paste it into a plain-text editor. If the order is scrambled, the sentences are broken, or some sections are missing, a parser will likely have the same problem. Fix the layout, then test again.
Next, compare your resume against a specific job description. The AcuRole audit shows which requirements your resume covers and which it doesn't, so you can edit the wording for the requirements you really have.
Frequently asked questions
Is one column always better?
For most roles, yes. A single column with clear headings is the easiest format for both software and people to read.
Should I include keywords in white text?
No. Hidden text is easy for recruiters to notice, and it can get your application rejected. Use the job's terms in visible text where they describe your experience.
Does a higher match score guarantee an interview?
No. A match score is a guide for editing your resume. Interviews depend on many factors outside the document.
