Short answer: An applicant tracking system (ATS) is recruiting software that stores and organizes application information. An ATS-friendly resume uses clear headings, truthful job-specific language, and a text-selectable layout so both software and people can understand the evidence you provide.
Key takeaways
- ATS products and employer workflows differ; there is no universal score or cutoff
- Match vacancy terminology only where it truthfully describes your experience
- Prefer standard headings and a simple, text-selectable reading order
- Follow the employer's file instructions instead of relying on a format guarantee
What is an ATS and what can it do?
ATS is a broad category, not one algorithm. Employers may use these systems to collect applications, search records, coordinate reviews, or support later assessment steps. Some workflows include AI-assisted CV sorting; the European Commission lists AI tools used for recruitment, including CV-sorting software, as a high-risk use case under the EU AI Act. That classification does not mean every ATS uses AI or rejects candidates automatically. See the Commission's AI Act overview.
How should you match your resume to a vacancy?
Start with the vacancy notice. Identify the required tools, responsibilities, and domain terms, then use the same wording where it accurately matches your record. If the role asks for "project management" and that is what you did, use that phrase and add a concrete example. Do not add a skill merely to trigger a keyword match.
Spell out an important term once before its acronym, such as "Customer Relationship Management (CRM)." This improves clarity for a reviewer and makes both forms searchable without guessing how a particular system tokenizes text.
Which seven changes improve resume readability?
1. Use familiar section headings
Labels such as "Work Experience," "Education," "Skills," and "Languages" make the document easy to scan. Creative labels can hide the meaning of a section from a busy reviewer even when software parses the words correctly.
2. Keep a predictable reading order
A single main column is the lowest-risk structure. If you use sidebars or tables, copy the text into a plain-text editor before submitting and confirm that names, dates, and bullet points remain in the intended order.
3. Write evidence, not keyword lists
Connect each relevant skill to an action and result. "Built a monthly forecasting model in Excel that shortened reporting by two days" is more useful than repeating "Excel" several times. Keep every number accurate and explain its context.
4. Follow the requested file format
Use the format named in the vacancy or application form. When both PDF and DOCX are accepted, choose a text-based file you have opened and checked after export. A scanned image may prevent text selection and can also create accessibility problems.
5. Put essential details in the main content
Keep your name, contact details, role history, and dates in the document body. Decorative headers, footers, icons, and charts should never be the only place where important information appears.
6. Tailor the summary and strongest bullets
A tailored resume is not a rewritten identity. Prioritize the experience most relevant to this role, update the short profile, and move the strongest matching evidence higher. Europass likewise advises candidates to focus on facts and main points that match the job.
7. Review the extracted text and the human view
Read the final document on desktop and mobile, then select and copy its text. Check that dates, special characters, and bullet order survive. Finally, ask another person whether the first page makes your fit clear without the vacancy beside it.
Why does skills evidence matter across Europe?
The European Labour Authority's 2025 report records 2,617 shortage reports and 2,177 surplus reports across EURES countries. It also notes that many occupations are in shortage in some countries and surplus in others. That is not a promise of demand for any individual candidate; it is a reason to describe portable skills precisely rather than relying on a job title alone. Read the ELA/EURES labour-shortage report.
How can you check an ATS-friendly resume?
- Confirm every required skill you claim is supported by a real example.
- Check that headings, employer names, titles, and dates appear in copied text.
- Remove repeated keywords that do not add evidence.
- Use the employer's upload preview when one is available.
- Keep a clean base version, then save a clearly named copy for each role.

ATS optimization is risk reduction, not a way to guarantee an interview. Make the resume accurate, relevant, readable, and easy to extract.

What are the most common ATS questions?
What is an applicant tracking system?
It is recruiting software used to collect and organize application information. Features differ by product and employer, so there is no single universal ATS score or cutoff.
How can I improve an ATS-friendly resume?
Use truthful vacancy terminology, familiar headings, relevant evidence, and a simple text-selectable layout. Then inspect both the extracted text and the human-readable file.
Should I submit PDF or DOCX?
Follow the vacancy's instructions. If both are allowed, submit a text-based file that preserves its reading order after export and opens correctly on another device.
Does an ATS automatically reject every low-scoring resume?
No universal workflow exists. Systems and employer processes vary, so avoid claims about a fixed score, cutoff, or automatic rejection unless that employer explains its process.
