ATS optimization guide
How to get your resume past applicant tracking systems
Most large company applications are screened by ATS software before a human sees them. Here is how to optimize your resume to pass ATS screening without making it unreadable for human reviewers.
What ATS actually does (and what it does not do)
Applicant Tracking Systems (ATS) like Workday, Greenhouse, Lever, and Taleo parse your resume into a structured database and screen candidates by keyword matching, experience, and education.
The myth
They do notscore your resume on a 1–100 scale and automatically reject below a certain threshold. That is a myth perpetuated by services selling “ATS optimization tools.”
What actually happens
ATS extracts information and allows recruiters to filter by keywords. What that means for you: the keywords in the job description need to appear somewhere in your resume.
The keyword matching approach
Four steps to close the gap between your resume and any job description.
Example
A data analyst JD that mentions “SQL, Tableau, Python, A/B testing, and stakeholder communication” needs those exact terms in your resume if you have that experience.
Formatting rules for ATS compatibility
These are not stylistic preferences. Each rule addresses a specific way ATS parsers fail to read resumes correctly.
Use standard headers: Work Experience, Education, Skills. Avoid creative headers like 'My Journey' or 'What I Have Done.'
No tables, columns, or text boxes. ATS parsers struggle with multi-column layouts. Use a single-column format.
Name and contact details should be in the body, not the Word header. ATS parsers often skip header and footer regions entirely.
Submit as .docx or .pdf. Both are generally safe with modern ATS. When in doubt, .docx is more universally parseable.
Use plain text checkmarks (✓) at most — images, icons, and decorative elements are not read by ATS.
What human reviewers care about that ATS does not
Once past the ATS, your resume is read by a human for 6–10 seconds. At that stage, quantified impact, clear writing, and logical structure matter more than keyword density. Optimize for ATS to get through the gate; optimize for humans once you are through it.
Quantified impact
Reduced churn by 18%
Clear writing
No jargon, no filler phrases
Logical structure
Most relevant information first
