What you need to know to prevent your CV from being rejected before it reaches people.

What is ATS? What you need to know to prevent your CV from being rejected before it reaches people.

Today, many companies filter job applications through software called ATS (Applicant Tracking System) instead of sending them directly to human resources teams.

These systems automatically analyze submitted CVs and score them according to specific criteria, forwarding only the most suitable candidates to human resources.

In other words:

Your CV is first read by software, then by a human.

If your CV isn't ATS-compliant, it may be rejected without even being seen, even if you're a very good programmer, designer, or manager.

How does ATS work?

ATS systems essentially do three things:

  1. It parses (separates) the text within the CV.
  2. It analyzes keywords.
  3. Calculates the job posting match score.

For example, if a job advertisement mentions the following technologies:

  1. Laravel
  2. REST API
  3. Docker
  4. MySQL

ATS systems search your CV for these keywords and assign a score based on the match rate .

Key Elements ATS Systems Looks For in a CV

ATS systems pay particular attention to the following sections:

1. Professional Summary

A brief summary located at the top of the CV.

Example:

Senior Full-Stack Developer specializing in Laravel, Symfony and scalable SaaS platforms. Experienced in REST APIs, Docker based deployments and multi-tenant architectures.

This section is very important from an ATS perspective because keywords are usually concentrated here.

2. Skills Section

ATS systems primarily analyze the skills section.

For a sample software developer:

Skills
• PHP
• Laravel
• Symfony
• REST API Development
• MySQL
• Docker
• Go
• CI/CD
• JWT Authentication
• SaaS Architecture

3. Experience Section

ATS systems analyze not only the job title but also the work performed.

A weak example:

PHP Developer
API development

A strong example:

• Developed RESTful APIs using Laravel
• Built scalable multi-tenant SaaS architecture
• Implemented JWT based authentication
• Managed CI/CD pipelines and Docker deployments

ATS's Least Favorite CV Mistakes

Many CVs are rejected not because of poor content, but because of incorrect formatting .

The most common mistakes:

1. Use of graphics and icons

ATS cannot read some characters.

For example:


Instead, the following should be used:

-

2. Complex design

ATS systems have difficulty reading the following structures:

  1. two-column CV
  2. text box
  3. layout created with a table
  4. graphic skill bars

The safest format:

Single column and plain text.

3. PDF format is not always safe.

Some ATS systems cannot correctly parse PDF files.

The safest format:

DOCX

4. CV in a mix of Turkish and English.

International ATS systems generally operate in English.

Example error:

Professional Experience
Project Manager

More accurately:

Professional Experience
Project Lead / Software Developer

  1. Use a simple design.
  2. Use a single-column layout.
  3. I prefer the DOCX format.
  4. Use the keywords in the job advertisement.
  5. Keep the Skills section extensive.

Frequently Asked Questions

Why is my CV rejected before reaching a recruiter?

Most companies use an Applicant Tracking System (ATS) to screen CVs before a human reviews them. If your CV doesn’t meet certain criteria such as keywords, formatting, or relevance, it may be automatically rejected.

How does an ATS evaluate a CV?

An ATS scans your CV, analyzes its content, and compares it with the job description. If your CV lacks relevant keywords or uses an incompatible format, it may receive a low score and be filtered out.

How can I create an ATS-friendly CV?

To make your CV ATS-friendly:

Use keywords from the job description

Choose a simple, single-column layout

Use standard headings (e.g., Experience, Skills)

Save your CV as a .docx or compatible PDF

What mistakes cause a CV to be rejected by ATS?

Common mistakes include:

Using graphics, icons, or tables

Submitting in an unsupported file format

Missing important keywords

Using complex or multi-column layouts

These issues can prevent ATS from properly reading your CV.

What is the most important factor to pass ATS screening?

The most important factor is using relevant keywords that match the job description. ATS systems rank and filter CVs based on how well they align with these keywords.
