What is an ATS and How to Make Sure Your Resume Doesn't Get Lost in the System?
The Silent Rejection: Your Perfect Resume Was Never Actually Seen
"We've reviewed your application and have decided to pursue other candidates..." In the shadows of modern hiring, up to 75% of qualified candidates are automatically rejected by Applicant Tracking Systems (ATS) before a human ever sees their application. Your experience, skills, and potential are reduced to a compatibility score — and if you don't know how to communicate with these digital gatekeepers, you're essentially invisible.
Let's decode what's really happening behind those automated rejections — and how to ensure your resume breaks through the algorithmic barrier and into human hands.

The Silent Rejection: Your Perfect Resume Was Never Actually Seen
"We've reviewed your application and have decided to pursue other candidates..."
In the shadows of modern hiring, up to 75% of qualified candidates are automatically rejected by Applicant Tracking Systems (ATS) before a human ever sees their application. Your experience, skills, and potential are reduced to a compatibility score — and if you don't know how to communicate with these digital gatekeepers, you're essentially invisible.
Let's decode what's really happening behind those automated rejections — and how to ensure your resume breaks through the algorithmic barrier and into human hands.
What Exactly Is an ATS and How Does It Work?
An Applicant Tracking System (ATS) is software that manages the hiring process, acting as both database and filtering mechanism. But understanding its inner workings is crucial to navigating it successfully.
The Evolution from Database to Gatekeeper
Early ATS platforms were simple databases that organized applications. Today, they're sophisticated filtering systems using complex algorithms to evaluate candidates against specific criteria.
Modern ATS systems:
Parse your resume into searchable components
Score applications based on keyword relevance
Filter candidates using preset qualification parameters
Rank applicants based on perceived match quality
How Your Resume Gets Processed
When you submit an application through job hunting sites or company portals, here's what happens behind the scenes:
Document Conversion: Your resume is converted into a plain text format, stripping formatting
Data Extraction: The system attempts to identify standard information (name, contact details, work history, education)
Parsing: Content is categorized and stored in the ATS database
Scoring: Your application receives a ranking based on match criteria
Filtering: Based on your score, your application either advances or gets filtered out
This process happens in seconds, with most systems spending less than 10 seconds "reading" your entire professional history.
The 7 Critical ATS Mistakes Costing You Interviews
No one wants to spend hours crafting the perfect resume only to have it disqualified by software. Here are the most common ATS pitfalls and how to avoid them:
1. Formatting That Confuses the System
Complex formatting that impresses humans often confuses ATS systems.
Common formatting mistakes:
Using tables, text boxes, or columns to organize information
Including headers/footers with critical information
Embedding graphics, charts, or images
Using creative but non-standard section headings
Implementing complex design elements
ATS-friendly alternatives:
Stick to standard chronological or functional formats
Use clear, conventional section headings (Experience, Education, Skills)
Maintain simple, consistent formatting throughout
Save as .docx or PDF (check which the specific system prefers)
Avoid headers, footers, text boxes, and tables
2. Missing the Keyword Match
ATS systems are essentially matching engines looking for alignment between your resume and the job description.
Keyword mistakes:
Using different terminology than the job description
Failing to include technical skills mentioned in the listing
Missing industry-specific certifications or qualifications
Not incorporating both spelled-out terms and acronyms (e.g., "Search Engine Optimization (SEO)")
Keyword optimization strategy:
Analyze job descriptions for recurring technical terms and skills
Include exact matches (not just synonyms) for critical requirements
Incorporate both full terms and acronyms where relevant
Ensure keyword density without obvious "keyword stuffing"
Use an ATS resume checker to identify missing keywords
3. Non-Standard Section Headings
ATS systems look for conventional resume sections to properly categorize your information.
Problematic headings:
"My Journey" instead of "Work Experience"
"Brain Power" instead of "Education"
"Tech Wizardry" instead of "Technical Skills"
ATS-friendly headings:
Work Experience/Professional Experience
Education
Skills/Technical Skills
Certifications
Publications/Presentations (if relevant)
4. Unconventional File Types
Some ATS systems struggle with certain file formats, potentially corrupting your carefully crafted resume.
Risky file formats:
.pages (Mac-specific)
.rtf (Rich Text Format)
PDF (in some older systems)
Custom formats from design software
Safe file formats:
.docx (Microsoft Word)
PDF (for newer ATS systems)
Plain text as backup
When applying through Linkedin jobs or Indeed job hunting platforms, research which file formats their systems handle best.
5. Missing or Inconsistent Employment Data
ATS systems look for patterns in your work history, including complete date ranges and logical progression.
Data problems that trigger rejection:
Missing employment dates
Inconsistent date formats
Unexplained gaps
Job titles that don't match conventional roles
Data optimization approach:
Use consistent date format (MM/YYYY)
Include both month and year for all positions
Ensure job titles align with industry standards
Address gaps with truthful explanations
6. Overreliance on Visual Hierarchy
Many candidates use visual elements to guide the reader's eye, but ATS systems can't interpret these cues.
Visual elements that cause problems:
Using font size alone to indicate section headings
Relying on bold or italic formatting for structure
Using color to categorize information
Implementing creative but non-standard layouts
ATS-friendly alternatives:
Use clear text labels for all sections
Implement standard hierarchical organization
Ensure information is comprehensible even in plain text
Test your resume by converting to plain text to check readability
7. Contact Information Formatting Issues
Even if your resume passes content filters, poorly formatted contact information can make it impossible for recruiters to reach you.
Contact formatting problems:
Placing phone numbers in headers/footers
Using images or logos containing contact details
Formatting phone numbers with uncommon separators
Using creative but unclear email presentations
Contact information best practices:
Place all contact information in the main body
Use standard formatting for phone numbers
Ensure email address is in plain text, not hyperlinked
Include LinkedIn URL with standard formatting
How to Create an ATS-Optimized Resume: Step-by-Step
Creating an ATS-friendly resume doesn't mean sacrificing impact. Here's how to balance algorithm appeal with human engagement:
Step 1: Start With a Compatible Template
Begin with a structure designed for both ATS compatibility and human readability:
Choose a simple, clean layout
Implement standard section ordering
Use a single-column format for most sections
Select common, readable fonts (Arial, Calibri, Times New Roman)
Many job search apps and cv builder free tools offer ATS-optimized templates as starting points.
Step 2: Conduct Thorough Keyword Research
Before writing, gather intelligence on critical terminology:
Collect 3-5 similar job descriptions
Identify recurring technical skills, qualifications, and requirements
Note industry-specific terminology and certifications
Pay attention to how they describe soft skills
Document both spelled-out terms and acronyms
AI resume builder tools can automate this process, analyzing job descriptions to identify the most important keywords.
Step 3: Craft Your Content With Dual Audiences in Mind
Write for both the algorithm and the eventual human reader:
Front-load bullet points with relevant keywords
Begin achievements with strong action verbs
Include specific metrics and results
Maintain natural language flow despite keyword inclusion
Use standard industry terminology
Step 4: Implement Proper Keyword Placement
Strategic keyword distribution improves ATS scoring:
Include critical keywords in your summary/profile
Repeat key technical skills in both skills section and work experience
Ensure primary keywords appear in the first 2-3 bullets of your most recent roles
Incorporate keywords naturally in context, not as lists
Use exact matches for critical terms, not just synonyms
Step 5: Verify ATS Compatibility Before Submission
Test your resume before sending:
Use an ATS resume checker to identify potential issues
Convert to plain text to ensure all information remains accessible
Have someone else review for both technical compliance and readability
Test with different file formats if unsure which the company uses

If your exact title doesn't match industry standards, consider: "Senior Account Manager (equivalent to Senior Client Relationship Manager)"
For internal or company-specific titles: "Technical Solutions Specialist (Systems Administrator)"
2. Strategic Repetition

Include key technical skills in summary, skills section, and relevant work experiences
Repeat certifications in both dedicated section and relevant job descriptions
Ensure critical keywords appear at least 2-3 times throughout the document
3. Mobile Application Optimization
With more applications happening via job finder app platforms:
Keep file sizes under 5MB
Verify mobile readability of all content
Test on multiple devices if applying through job application tracker or mobile platforms
