What Is an ATS and Why Does It Matter?
An Applicant Tracking System (ATS) is software that employers use to collect, sort, and rank job applications. When you submit your resume online, it almost never goes directly to a human recruiter. Instead, it passes through an ATS that parses your resume, extracts key information, and scores it against the job description.
Research consistently shows that between 70% and 75% of resumes are rejected by ATS software before a human ever reads them. This isn't because candidates are unqualified — it's because their resumes aren't formatted or optimised for machine parsing.
How ATS Systems Work
Modern ATS platforms like Workday, Greenhouse, Lever, iCIMS, and Taleo use a combination of keyword matching, semantic analysis, and formatting checks to evaluate resumes. Here's what happens when you submit:
Step 1: Parsing. The ATS extracts text from your resume and attempts to identify sections (Contact, Experience, Education, Skills). If your formatting confuses the parser, data gets lost or misclassified.
Step 2: Keyword matching. The system compares your resume against the job description, looking for exact and near-exact keyword matches. Missing critical keywords means a lower score.
Step 3: Ranking. Candidates are ranked by their match score. Only the top-ranked resumes are typically reviewed by a human recruiter.
The 7 Most Common ATS Failure Points
1. Using Tables, Text Boxes, or Columns for Layout
Most ATS systems read documents linearly, left to right, top to bottom. When you use tables or text boxes, the parser reads across columns in the wrong order, scrambling your information. Use a single-column layout with standard section headers.
2. Using Headers and Footers for Contact Information
Many ATS parsers cannot read text inside document headers and footers. If your name, phone number, or email is in the header, the system may not capture it. Place all contact information in the main body of the document.
3. Non-Standard Section Headings
ATS systems are trained to recognise standard section names. "Professional Journey" confuses a parser that expects "Work Experience." Stick to: Work Experience, Education, Skills, Certifications, Summary.
4. Missing Keywords from the Job Description
This is the single biggest reason resumes fail ATS screening. Read the job description carefully and mirror its exact language. If the JD says "project management," don't just write "managing projects." Use the exact phrase.
5. Submitting as an Image PDF
A scanned resume or a PDF created from an image cannot be parsed at all — the ATS sees a blank document. Always submit a text-based PDF or DOCX file.
6. Fancy Fonts and Special Characters
Decorative fonts, icons used as bullet points, and special characters can corrupt parsing. Use standard fonts (Arial, Calibri, Times New Roman) and standard bullet points.
7. Inconsistent Date Formatting
ATS systems parse dates to calculate tenure. Use a consistent format throughout: "January 2022 – March 2024" or "01/2022 – 03/2024." Mixing formats causes parsing errors.
The ATS-Optimised Resume Checklist
Format: Single-column layout, standard fonts at 10–12pt, no tables or text boxes, contact information in the document body (not header/footer), saved as text-based PDF or DOCX.
Content: Standard section headings, keywords from the job description used naturally throughout, job title from the posting mentioned in your summary, consistent date formatting, quantified achievements.
Keywords: Hard skills mentioned in the JD (software, tools, methodologies), soft skills mentioned in the JD, industry-specific terminology, certifications spelled out in full.
How to Find the Right Keywords
Paste the job description into a word frequency tool and identify the most-repeated terms. These are the keywords the employer considers most important. Use these keywords naturally in your bullet points, summary, and skills section. Don't keyword-stuff — modern ATS systems and human reviewers both penalise obvious stuffing.
Testing Your Resume Against ATS
Before submitting, test your resume using an ATS simulator. ResumeScribe.ai's built-in ATS scanner analyses your resume against any job description and gives you a score with specific improvement suggestions. Aim for a score of 80 or above before submitting.
The Bottom Line
Beating ATS systems isn't about gaming the system — it's about communicating clearly and professionally in a format that both machines and humans can understand. Start with a clean template, use relevant keywords, and let ResumeScribe.ai's AI help you optimise the rest.
