How to Pass an ATS Resume Scan: What Actually Works

To pass an ATS resume scan, your resume has to do two things: the software has to be able to read it, and it has to match the criteria the employer set. Readable means one column of real text, standard headings, full job titles and your contact details in the body of the page rather than in a header. Matching means using the job posting's own words for the titles and skills you really have, and answering the application's screening questions accurately. The risk is real but specific: in a Harvard Business School survey, 88% of employers said qualified high-skills candidates are screened out because they don't match the exact criteria in the job description.

We make YoodaAI (about us), which includes an ATS resume builder. What we say about how applicant tracking systems behave comes from the sources linked below, mainly Greenhouse's documentation and the Harvard Business School study.

What an ATS does with your resume

An applicant tracking system (ATS) is the software an employer uses to receive applications and move candidates through hiring. It reads your resume into fields, such as your name, job titles, employers, dates and skills, so recruiters can search, filter and rank applicants.

Harvard Business School and Accenture's 2021 study Hidden Workers: Untapped Talent surveyed 2,275 executives in the US, the UK and Germany. More than 90% of their employers used recruiting systems to filter or rank candidates at the first stage (Harvard Business School).

That filtering is where qualified people get lost. In the same survey, 88% of employers agreed that qualified high-skills candidates are vetted out because they don't match the exact criteria in the job description, and 94% said so for middle-skills candidates. Almost half of the companies screened out resumes with a gap in work history, and for gaps longer than six months, their systems did it automatically on that basis alone.

You may also have read that 75% of resumes are rejected by ATS before a human sees them. We couldn't find a published study behind that figure. The documented risks are narrower, and you can act on each of them.

The four ways an ATS can stop a resume

Step 1: Make sure the ATS can read your resume

Greenhouse, an applicant tracking system, publishes the reasons a resume fails to parse (Greenhouse Support). As a checklist:

• One column. Columned layouts are on the list, and so are tables.
• No headers or footers for anything important. Name and contact details in a header, footer or text box can be missed, so keep them in the body of the page.
• Real text, not pictures. Graphics, photos and word art can fail, and so can a resume uploaded as an image rather than a document.
• No spaced-out letters. A name written as "J O H N" looks fine to you, but the parser won't read the letters as one word.
• Clear, standard sections. "Work experience" and "Education", formatted the same way throughout.
• Full job titles. Greenhouse's example is "Sr. Account Exec" instead of "Senior Account Executive".
• Recognisable company names. Greenhouse notes that names without words such as Inc., Co., Ltd or LLC can be harder to pick out. If an employer's name doesn't sound like a company, its legal suffix helps.
• A file under 2.5 MB. Greenhouse can't parse larger resumes.

As for the file type, Greenhouse accepts .doc, .docx, .pdf, .rtf and .txt uploads (Greenhouse Support), so a PDF made of real text and a Word file both work there. If a posting asks for a particular format, use that one.

Step 2: Match the criteria the employer set

Exact-criteria filtering means the words matter, not just the experience behind them.

• Use the posting's job title where it's true. Keep your real title, and if the posting calls the same job something else, use its term in your summary, such as "account manager (customer success)".
• Name skills the way the posting does. If it says "financial modelling", don't only write "forecasting". Write an acronym out once as well, like "search engine optimisation (SEO)", since a recruiter may search for either.
• Show skills in your bullet points, not only in a list. "Built a financial model for a $2 million expansion" proves the skill the list only names.
• Write credentials exactly as they appear in the posting. If it asks for a licence, degree or certification you hold, use the same name, so a search for it finds you.
• Don't stuff keywords or hide them in white text. Hidden text is still text: a parser can pull it into your profile, where a recruiter may see it.

Step 3: Explain gaps and answer screening questions carefully

If you have a gap of more than six months, don't leave it blank. Add a dated entry for what you did, such as studying, caring for a family member, freelancing or volunteering. Whatever the software does with dates, it shows a recruiter what happened instead of an empty space.

Screening questions can matter more than the resume. Greenhouse lets employers reject applicants automatically based on their answer to a yes/no, single-choice or multiple-choice question. Its example is a driving job that rejects anyone who answers no to holding a Class A commercial driver's licence (Greenhouse Support). Read each question slowly, answer accurately, and don't click through them as a formality.

Step 4: Test the resume before you apply

• Do a copy-paste check. Open your PDF, select all the text and paste it into a plain text editor. If sections come out mixed together, out of order or missing, a parser may read them the same way.
• Check the fields an ATS fills. Name, email and phone, a job title, a month and year for every role, your education and your skills.
• Read it against the posting. Every requirement you meet should appear in your resume in the posting's words.

How YoodaAI's Resume Studio helps

YoodaAI's ATS resume builder, in Resume Studio, lays every resume out in one main column of real text under standard headings, so the layout takes care of most of step 1. As you type, it scores the content out of 100 from 8 checks of equal weight:

• contact details
• a target job title
• a summary of at least 80 characters
• a role with a job title, a company and a start date
• at least two bullet points in a role
• a number in at least one bullet
• education
• at least 5 skills

Building a resume and checking its score are free, and each PDF download is 5 credits. New accounts start with 20 free credits.

If you already have a resume, the ATS resume checker reads it as a PDF or Word file and scores it out of 100 for an ATS and then a recruiter. It lists three to eight things to fix, most important first, each with a rewrite you can apply, and warns you when a PDF is a scanned image that most ATS can't read. A check is 5 credits. The score checks what parsers and recruiters look for; it isn't a copy of any employer's system, and no checker can see an employer's filters. If you would rather start from a file, three free templates, Classic, Modern and Structured, download without an account.

Frequently asked questions

Do applicant tracking systems reject resumes automatically?

Some rules do. Employers can reject applicants automatically based on their answers to screening questions, as Greenhouse's auto-reject feature allows. The Harvard Business School study also found almost half of companies screened out resumes with gaps in work history, automatically in the case of gaps longer than six months. We couldn't find published evidence for the claim that ATS reject 75% of resumes.

Should I send a PDF or a Word file?

Either usually works: Greenhouse, for example, accepts .doc, .docx, .pdf, .rtf and .txt. Make sure a PDF is made of real text rather than a scanned image, and follow the posting if it asks for a particular format.

Can I use a two-column resume?

It's a risk. Greenhouse lists columned layouts, tables, headers, footers and text boxes among the reasons a resume fails to parse. One main column is safer.

Does an ATS score predict whether I'll get an interview?

No. A score can tell you whether your resume has the content and format that parsers and recruiters look for, but not how a particular employer has set its filters. Use it to catch gaps, then match the resume to each posting.

The short version
