What Are ATS Checks —
And How Do You Overcome Them?
Applicant Tracking Systems are software used by employers to manage, filter, and rank job applications automatically. If your resume doesn't pass the ATS check, no human ever sees it — no matter how qualified you are. Here's exactly how these systems work and what you can do about it.
What is an ATS check, exactly?
When you submit a job application online, your resume almost never goes directly to a human. It goes into an Applicant Tracking System — software like Workday, Greenhouse, Lever, Taleo, iCIMS, or BambooHR — which automatically processes it before a recruiter ever opens the application.
The ATS performs a series of automated checks:
Parsing — converting your resume into structured data
The ATS extracts your name, contact info, job titles, dates, employers, education, and skills into a structured database. Poorly formatted resumes (columns, tables, text boxes) lose content at this stage — the system simply can't read it.
Keyword matching — comparing you to the job description
The system scans your parsed resume for keywords from the job description — hard skills, tools, qualifications, job titles, and action verbs. Your "match rate" becomes the primary input into your ranking score.
Ranking — sorting all applicants by score
Every applicant gets a score. Recruiters are shown the top 10–20%. Below that threshold, applications may never be opened. The cut-off varies by company and volume of applicants, but it's almost always present.
The core problem: Two candidates with identical experience can get radically different scores depending on how they've written their resume. The one who matches the JD's exact language ranks higher — even if their actual experience is equivalent.
What ATS checks are actually looking for
Understanding the criteria helps you target your optimisation effort:
- Exact keyword matches — terms from the job description that appear verbatim in your resume. "Stakeholder management" vs "managing stakeholders" can be treated as a non-match by some systems.
- Semantic matches — more advanced ATS systems (and AI-powered ones) understand synonyms and related concepts. Claude AI (used by ATSCheck) excels here.
- Required qualifications — hard requirements like degree level, years of experience, and certifications are often used as binary knock-out filters before scoring even begins.
- Formatting compatibility — whether your resume can be parsed cleanly. Single-column, plain-text-friendly layouts score higher than complex designed formats.
- Section completeness — missing standard sections (Experience, Education, Skills) signals an incomplete resume to some systems.
Common ATS myths — busted
"A beautifully designed resume with columns and icons shows effort and creativity."
Designed resumes with columns and graphics often parse as blank or garbled. ATS systems read plain text — not visual design.
"Keyword stuffing your resume with every term from the JD will boost your score."
Adding keywords you don't have experience with is dishonest and will fail at interview. Only add keywords for skills you genuinely possess.
"One great resume can be used for every application."
ATS scores are job-specific. A resume scoring 90 for one role may score 55 for another. Tailoring is essential for every application.
"Using white text to hide keywords tricks the ATS into a higher score."
Modern ATS and recruiter platforms flag this immediately. It's considered resume fraud and will result in automatic disqualification.
How to overcome every ATS check
Fix your formatting first
Switch to a single-column layout. Remove tables, text boxes, and graphics. Use standard section headers. Save as .pdf or .docx. This alone eliminates the most common ATS failure mode.
Match the JD's exact language
Don't paraphrase skills — mirror the exact phrasing used in the job description. Run your resume through ATSCheck to see exactly which keywords are missing.
Target 75+ on your score
Use ATSCheck to score your resume before applying. Below 70 and you risk being filtered automatically by competitive roles. Make targeted edits and recheck until you're above 75.
Tailor for every application
Keep a "master" resume with all your experience, then create a tailored version for each application. Even 10 minutes of tailoring per role can double your interview rate.
Meet the hard requirements
If a job lists required qualifications as non-negotiable (specific degree, years of experience, certifications), the ATS may filter you out regardless of score. Only apply if you meet these hard requirements.
Write both acronyms and full terms
"Project Management Professional (PMP)" ensures you match searches for either form. Apply this to all certifications, tools, and technologies on your resume.
What happens after you pass the ATS?
Clearing the ATS filter is step one — not the finish line. After your resume ranks in the top tier, a human recruiter will typically review it in 3–6 seconds. That initial scan checks for: a clear job title match, a readable summary, quantified achievements in your bullet points, and a logical career progression.
This is why ATS optimisation and good resume writing go hand in hand. Getting through the filter with a keyword-dense but poorly written resume will still result in rejection. The best approach is a resume that's both ATS-optimised and compelling to a human reader — and those two goals are much more compatible than most people think.
