Many employers use software to read, sort and rank CVs before a person looks at them.

EQF Level 4–5

By the end of this lesson you can

  • Explain what an ATS is and how it screens CVs

Read the lesson

Many employers use software to read, sort and rank CVs before a person looks at them. In this lesson you learn how this software, called an ATS, works. You will use AI to make your CV clear, honest and easy for the software to read.

01Why ATS matters

Many CVs are filtered out by software before a person ever reads them.

70%

of large EU employers use an ATS

45%

of EU small and medium-sized companies use an ATS

If the software cannot read your CV, a person may never see it.

02Your CV has two readers

A strong candidate can be rejected just because the software could not read the CV.

The good news: a few simple changes make your CV work for both software and people.

03How an ATS reads your CV

A simple view of what happens after you click "Apply".

  1. You apply. You upload your CV to the company's job website.
  2. Parsing. The software reads your CV and sorts it into sections: experience, education, skills.
  3. Matching. It compares your CV with keywords and criteria from the job advert.
  4. Ranking. It ranks candidates. The best matches go to a recruiter to read.
04ATS-friendly CV: best practice

Format your CV so it passes automated screening.

  • Standard headings. Use clear sections such as Experience, Education and Skills. Avoid creative labels.
  • Keywords. Include keywords from the job description naturally throughout your CV.
  • Clean layout. Avoid tables, graphics, headers and footers. Use one column, saved as .docx or .pdf.
05CARE example: rewriting a CV point

Original CV point: "Responsible for various tasks in marketing".

CARE element Example prompt
Context I am applying for a Digital Marketing Specialist role at a Spanish e-commerce company. The job focuses on SEO, content and analytics.
Action Rewrite this CV point to be more specific and include relevant keywords.
Result Make it action-oriented, include real results if possible, and keep it under 20 words.
Example Use strong action verbs like "developed", "managed" or "increased".
AI output "Developed and executed SEO content strategy, increasing organic traffic by 35% over 6 months."

Only keep numbers that are true. If you did not measure 35%, change or remove it.

06Using AI on your CV: do and don't

AI can improve your CV, but you are responsible for every word.

Do

  • Paste the job advert and ask for matching keywords
  • Ask AI to make your points clearer and shorter
  • Tell the AI: "Do not invent any experience"
  • Read every line and correct anything untrue

Don't

  • Accept skills or results you do not have
  • Copy the job advert word for word
  • Hide keywords in white text
  • Send the CV without reading it yourself
07Common ATS mistakes to avoid

Test your CV with a free ATS checker before you apply.

  • Creative layouts. Icons, infographics and unusual fonts confuse ATS software.
  • Keyword stuffing. Too many unnatural keywords look like spam and are hard to read.
  • Only abbreviations. Write terms in full the first time: "Search Engine Optimisation (SEO)", not just "SEO".
