Reminder: An ATS (Applicant Tracking System) is software that automatically filters resumes before a recruiter sees them. 75% of resumes are rejected by these filters. Learn more about ATS β†’

1

Choose the Right Resume Format

Your resume format is crucial for the ATS. A poor choice can make your resume completely unreadable by the software, even if the content is perfect.

To do

  • βœ“ Single column from top to bottom
  • βœ“ A4 vertical format (portrait)
  • βœ“ Standard margins (0.8-1 inch)
  • βœ“ Readable font: Arial, Calibri, or fonts embedded in the PDF
  • βœ“ 10-12pt size for body text

To avoid

  • βœ— Multiple columns (mixed text)
  • βœ— Tables to structure content
  • βœ— Headers/footers with important information
  • βœ— Non-embedded fonts in the PDF
  • βœ— Text in images

πŸ’‘ Tip: To check if your resume is ATS-friendly, copy-paste the content of your PDF into a text editor. If the text appears in the correct order and is readable, that's a good sign!

Note on fonts: If you create your resume manually with Word or Google Docs, prefer system fonts (Arial, Calibri). Professional generators like JobAlign use more elegant fonts but properly embedded in the PDF, which ensures their readability by ATS systems.

Structure Essential Sections

An ATS-friendly resume must contain clearly identified sections with standard titles that the ATS easily recognizes.

Recommended structure (in this order)

1

Header / Contact Information

Name, phone, email, city, LinkedIn (optional)

2

Title / Professional Summary

2-3 lines summarizing your profile and objective

3

Work Experience

From most recent to oldest (reverse chronological order)

4

Education

Degrees, certifications, relevant training

5

Skills

Technical and soft skills, organized by categories

+

Optional: Languages, Interests

Only if relevant for the target position

Recommended section titles: Use standard headings like "Work Experience", "Education", "Skills". Avoid original titles like "My Journey" or "What I Can Do" that the ATS might not recognize.

3

Write the Header and Summary

The header is the first thing the ATS and recruiter see. It must be clear, complete and well formatted.

"Full-Stack Developer with 5 years of experience in React and Node.js. Specialized in creating performant and scalable web applications. Passionate about development best practices and user experience."

βœ“ Best practices for the summary

  • β€’ Include the target job title
  • β€’ Mention your years of experience
  • β€’ Add 2-3 key skills
  • β€’ Stay concise: 2-3 lines maximum

πŸ’‘ ATS Tip

Use in your summary the main keywords from the job posting. If the ad mentions "Digital Project Manager", use exactly these terms rather than "Digital Projects Manager".

4

Write Work Experience

This is the most important section of your resume. Each experience must be structured consistently and include quantified results.

Typical experience structure:

Full-Stack Developer

| TechCorp Inc. | New York, NY

January 2021 - Present

  • β€’ Developed an e-commerce application in React/Node.js serving 50,000 monthly users
  • β€’ Optimized site performance, reducing loading time by 40%
  • β€’ Mentored a team of 3 junior developers on Agile methodologies
  • β€’ Implemented a CI/CD system with GitHub Actions, reducing deployment times by 60%

Magic formula: Action verb + Task/Project + Quantified result + Technologies used

Recommended action verbs by category:

Leadership

Led, Supervised, Coordinated, Mentored, Managed, Directed

Creation

Developed, Designed, Created, Launched, Initiated, Founded

Improvement

Optimized, Improved, Enhanced, Restructured, Modernized

πŸ’‘ Crucial advice: Adapt your bullet points to each posting. If the position requires experience in "project management", highlight your achievements in this area, even if it wasn't your main responsibility.

5

Optimize the Skills Section

The skills section is crucial for the ATS because that's where it looks for keywords first. It must be clear, organized and relevant.

Example of a well-structured skills section:

Languages & Frameworks

JavaScript (ES6+), TypeScript, Python, React, Node.js, Express, Next.js

Databases

PostgreSQL, MongoDB, Redis, MySQL

Tools & Methods

Git, Docker, AWS, CI/CD, Agile/Scrum, Jest, Cypress

Soft Skills

Project management, Client communication, Teamwork, Problem-solving

βœ“ To do

  • β€’ List skills in plain text
  • β€’ Use the exact terms from the posting
  • β€’ Include acronyms AND full versions
  • β€’ Organize by logical categories
  • β€’ Prioritize requested skills

βœ— Absolutely avoid

  • β€’ Gauges or progress bars (ignored by the ATS)
  • β€’ Ratings out of 5 or percentages
  • β€’ Icons or graphics
  • β€’ Skills not relevant to the position
  • β€’ List too long (max 15-20 skills)

Why no gauges? The ATS cannot interpret an 80% progress bar. Moreover, a recruiter might wonder why you're only at 80% and not 100%. Simply list your skills.

Fatal Errors to Avoid

These errors can cause your resume to be rejected instantly, even if you're the perfect candidate.

1. Multiple columns

The ATS reads left to right, line by line. Two columns create text that is completely mixed and incomprehensible to the software.

2. Invisible tables

Even if you don't see the borders, tables used for layout completely disrupt ATS parsing.

3. Information in header/footer

Many ATS systems completely ignore these areas. Put your contact information in the body of the document.

4. Scanned PDFs or images

If your resume is an image (scan, screenshot), the ATS cannot extract any information. Use a native text PDF.

5. One resume for all applications

Without adaptation to each posting's keywords, your ATS score will be systematically low. Personalize for each application.
