What you will learn
An applicant tracking system, or ATS, is recruitment software an employer may use to collect applications and manage a hiring process. Some systems extract information from a document into fields. Preparing a readable CV helps both software and people, but does not guarantee an interview.
- Understand what parsing can do and why platforms differ.
- Review headings, layout, file format, and truthful keywords.
- Test selectable text and reading order using a working checklist.
What recruitment software may do
An employer may use software to receive files, organise candidates, search records, coordinate stages, or extract details into fields. Parsing means trying to identify information such as names, dates, skills, or work history from a document.
Greenhouse documents a case in which a failed parse leaves the resume attached but requires manual entry of candidate details. This is one vendor’s behaviour, not proof of what every ATS does. A parsing problem and an automatic rejection are not the same thing.
Use conventional headings and a clear layout
Make it easy to distinguish contact details, summaries, experience, projects, education, and skills. Keep a sensible reading order and consistent date style. A straightforward one-column layout is a practical starting point when the employer has not requested something different.
- Use readable fonts and spacing; avoid letter spacing that splits ordinary words.
- Keep important text as actual text rather than only inside an image or decorative graphic.
- Avoid relying on icons, skill bars, or unusual section labels to communicate essential information.
- If you use columns, tables, headers, or text boxes, carefully test the saved reading order rather than assuming it will work everywhere.
- Follow employer instructions for accepted file type, size, and any required fields.
Choose and check the saved file
PDF and DOCX are common application formats, but the employer’s instructions take priority. Exporting to PDF does not automatically prove that the text is selectable or ordered well. A scanned picture of a CV is different from a text-based document.
This manual check is not a simulation of every ATS or an eligibility assessment. It can reveal obvious text and ordering problems before you apply.
- Save in the requested format and open that saved file.
- Try selecting the ordinary body text, including your name and contact details.
- Copy it into a plain-text editor and read from top to bottom.
- Check that dates, headings, bullets, and links remain understandable.
- Where an application shows extracted fields, review and correct them before submission.
Use relevant words naturally and truthfully
Read the vacancy to identify the capabilities being requested, then describe relevant work using accurate language. If you have built REST API integrations, explain the work rather than repeating “REST API” in every line.
Do not add tools you have not used, hidden text, white-on-white keywords, or a copied job description. Keywords should help explain evidence, not substitute for it. Expand unfamiliar abbreviations where that improves clarity.
Common ATS myths
There is no single public rule that describes every employer’s recruitment process. Treat sweeping claims with caution.
| Claim | What to do instead |
|---|---|
| Every complex layout is automatically rejected. | Check the specific instructions and saved text; systems and employer workflows vary. |
| PDF always works, or DOCX always works. | Use the requested file type and inspect the actual saved file. |
| A high keyword score guarantees an interview. | Match truthful evidence to requirements; hiring involves other criteria and decisions. |
| A failed parse proves the candidate is unsuitable. | Review extracted fields where available and distinguish document extraction from eligibility. |

Practical activity: test text and reading order
Work on a copy of your draft so you can compare versions.
- Open the actual file you intend to submit and copy its selectable text into a plain-text editor.
- Read it in order and note missing, interleaved, or confusing information.
- Simplify one problematic layout element and export again.
- Compare the two versions and review any application autofill if shown.
- Use the checklist to record checks completed, and follow the employer’s instructions before submitting.
