Why resumes get mangled
Applicant tracking systems (ATS) such as Workday, Greenhouse, Lever and Taleo extract the text from your file and sort it into fields: name, contact details, jobs, education and skills. Recruiters then search and filter on those fields. Designers' templates often use layouts that look clean to a person but confuse parsers:
- Tables and skill grids: cells are read one after another, sometimes with no spaces, so "Python", "SQL" and "Tableau" become "PythonSQLTableau" and a search for "SQL" misses you.
- Two columns: many parsers read straight across the page, mixing a line of your sidebar into the middle of a job description.
- Text boxes, headers and footers: often skipped entirely, which is a problem when your name and phone number live there.
- Icons instead of words: phone and email icons from icon fonts come out as unreadable characters.
- Creative headings: "Where I've made an impact" isn't recognised as your work experience.
The "What the parser reads" box shows your resume's text in the order it's stored in the file, with no layout, which is close to what an ATS works from. If it reads in a sensible order with your name on the first line, you're in good shape.
An ATS-friendly resume in short
- Single column, standard headings (Experience, Education, Skills).
- Name on the first line, then email and phone as plain text, in the body of the document.
- Job title, employer and dates (e.g. "Jan 2021 – Present") on each role.
- Skills as a comma-separated list or simple bullets, using the same words as the job ad.
- A standard font, saved as a text-based PDF or .docx, not a scan or image.
Using the keyword match well
Recruiters often search the ATS for specific skills and job titles. The keyword match picks out the most repeated words and phrases in the job ad and shows which ones your resume contains. Use the job ad's exact wording where it's honestly true for you, for example "stakeholder management" rather than "managing stakeholders". Don't paste in keywords you don't have: the person reading it afterwards will notice.
FAQ
Is this the same as a real ATS score?
No tool can show the exact result for every ATS, as each one parses and ranks differently. These checks cover the problems that break parsing most often, which is what decides whether your experience is read at all.
Why isn't my resume uploaded?
Resumes are full of personal information. The checker runs in your browser, so your file stays on your device and there's nothing to sign up for.
PDF or Word?
Both work in modern ATS. Follow the job ad if it asks for one. Whichever you send, make sure it's text-based (you can select the text) rather than an image.
