ATS Application 2026: The Complete Guide to ATS-Optimised Applications

An Applicant Tracking System (ATS) is software that automatically captures, sorts, and pre-filters applications. In Germany, over 70 % of medium-sized and large companies use an ATS to make the hiring process more efficient. For you as an applicant, this means: before a human reads your documents, an algorithm has already decided whether your profile is relevant. If you do not know the rules, you lose — regardless of your actual qualifications.

This guide shows you how ATS systems work, which software is widely used in Germany, and how to structure your application so it reliably passes through every automated filter. Want to know right away whether your application is ATS-ready? Then use our free ATS check.

What is an ATS? — Simply explained

ATS stands for Applicant Tracking System — in German: Bewerbermanagementsystem. It is software that digitises the entire recruiting process. From the moment an application arrives through to the pre-selection and final decision — everything runs through a central system.

When you submit your application via an online form or a company career page, this is what happens:

• Parsing: The ATS reads your document (PDF or DOCX) and extracts structured data — name, contact details, work experience, education, skills.
• Categorisation: Your data is converted into a standardised profile and compared against the advertised position.
• Scoring: Based on keywords, qualifications, and other criteria, you receive a relevance score.
• Filtering: Applications below a certain score are discarded or placed at the bottom of the pile.

For companies, this is efficient: instead of manually reviewing 300 applications, the system automatically checks which candidates meet the basic requirements. For applicants, this means: your documents must be machine-readable — otherwise you have no chance of being seen by a human at all.

The 10 most common ATS systems in Germany

Not every ATS works the same way. The software differs in parsing quality, keyword matching, and user-friendliness. Here are the ten systems you will encounter most frequently on the German market:

The takeaway for you: there is no single “one ATS”. Every system parses documents slightly differently. That is why you should format your application so that it can be reliably read by all common systems. That is exactly what ATS optimisation means.

Keyword matching: How an ATS reads your application

The heart of every ATS is the parser — an algorithm that converts your document into structured data. Three things happen in this process:

1. Text extraction

The ATS reads the text from your document. Images, graphics, tables in complex layouts, and embedded text fields are often ignored. If your name is in a header graphic, the system may not recognise it.

2. Keyword recognition

The system compares the extracted text against the job listing. Both exact matches and semantically related terms are considered — however, semantic recognition varies in sophistication depending on the system. The safe approach: use the exact terms from the job listing.

3. Scoring and ranking

Based on the keywords found, your work experience, and other criteria, the ATS calculates a score. Recruiters then see a list of all applications sorted by relevance. Whoever is at the top gets looked at first.

20-point ATS checklist

This checklist covers all relevant areas — from formatting to content. Go through every point before submitting your next application:

• Check the file format: Use text-based PDF or DOCX — never image PDFs or exotic formats.
• Clear section headings: “Work Experience”, “Education”, “Skills” — no creative alternatives like “My Journey”.
• Standard fonts: Arial, Calibri, Helvetica, or Times New Roman. No decorative typefaces.
• Font size 10–12pt: For body text. Headings may be larger.
• No tables for layout: Multi-column table layouts are misinterpreted by many parsers.
• No text fields or text boxes: Content in text boxes is often skipped entirely.
• No headers or footers for important information: Contact details belong in the document body.
• No graphics or icons for skills: Skill bars or star ratings are invisible to an ATS.
• Use keywords from the job listing: Verbatim, not paraphrased.
• Use the job title from the listing: If the role is called “Project Manager”, do not write “Project Lead”.
• Abbreviations and full forms: Use both variants (e.g. “SEO (Search Engine Optimization)”).
• Reverse-chronological order: Most recent experience first — that is what ATS and recruiters expect.
• Consistent date format: “01/2023 – 12/2025” or “January 2023 – December 2025” — stay consistent.
• Complete contact details: Name, email, phone, city — all as plain text.
• No special characters in headings: Avoid emojis, symbols, or unusual bullet points.
• Simple bullet points: Round dots or dashes. No custom bullets.
• Professional file name: “CV_FirstName_LastName.pdf” — not “CV_final_v3(2).docx”.
• File size under 5 MB: Larger files are rejected by some systems.
• No passwords or encryption: Protected PDFs cannot be parsed.
• Test before sending: Copy the text from your PDF into a plain text editor. Is everything readable and in the correct order? Then the document is ATS-compatible.

PDF vs. DOCX — which format ATS systems read better

This question comes up in almost every application consultation. The short answer: both formats work — if you follow a few rules.

PDF — the standard in Germany

PDFs are the preferred format in Germany. The layout remains identical on every device, and the file cannot be accidentally modified. The only thing that matters is that it is a text-based PDF — not a scanned document. Scanned PDFs are image files that no ATS can read.

DOCX — better for older systems

Some older ATS systems handle DOCX files better than PDFs. The downside: the layout can shift on different devices, and the file is editable. If the job listing explicitly requests DOCX, provide DOCX. Otherwise: PDF.

What you should avoid

In any case, avoid: .pages (Apple), .odt (LibreOffice), image PDFs from the scanner, and PDFs exported from Canva or similar design tools — these often contain text fragments in the wrong order. More on file formats in our article File formats and submission.

Myths vs. Reality

There are many half-truths circulating about ATS systems. Here we clear up the most common myths:

The myth about white text is particularly dangerous: modern ATS systems detect hidden keywords and classify them as manipulation. In the best case, this leads to your application being discarded; in the worst case, to a permanent note in the company's system.
