Inside the Machine
Understanding the usual ATS workflow helps you write a resume that is easier to parse and easier for recruiters to review.
When you submit your resume online, the ATS immediately extracts text from your file. It attempts to identify sections like contact info, work experience, education, and skills. Fancy formatting — tables, columns, headers/footers, text boxes, and embedded images — often breaks the parser, causing entire sections to be lost or scrambled. This is why ATS-optimized formatting is critical.
The system compares your resume content against the job description's required skills, certifications, tools, and qualifications. It looks for exact and semantic matches. If the job requires "Python" and your resume says "programming," that's often not a match. The more precisely your resume mirrors the job description's language, the higher your keyword match score.
Many systems rank resumes based on keyword match, section completeness, formatting clarity, and experience relevance. A cleaner resume helps the recruiter review the right information faster.
Recruiters still make the hiring decision. ATS-friendly formatting simply improves the chance that your experience is parsed correctly and presented clearly for review.

Check My ResumeThe Reality
Applicant Tracking Systems parse resumes based on formatting, keywords, and structure. Clean formatting helps your experience stay readable as it moves into recruiter review.
The safest resume is readable twice: first by the parser, then by the person making the shortlist.
standard headings help parsers preserve each resume section
role keywords help connect your experience to the job description
action verbs and outcomes make experience easier to evaluate
A two-column resume can look polished but still lose section order when parsed. The checker flags layout, missing role keywords, and vague bullets so the candidate can switch to a cleaner template and rewrite the highest-impact sections before applying.
Industry Insights
Different industries prioritize different keywords and formatting conventions. Here's what ATS systems in each sector are scanning for.
List specific programming languages, frameworks, and tools (Python, React, AWS). Include GitHub/portfolio links. Mention certifications (AWS, GCP, Cisco). Use metrics: "reduced latency by 40%", "scaled system to 1M+ users."
Quantify deal sizes, revenue impact, and portfolio value. Include compliance keywords (SOX, Basel III, GAAP). Mention modeling tools (Bloomberg, FactSet). Use metrics: "$2.3M deal closed", "15% cost reduction."
Include licensure numbers and certifications (RN, CNA, HIPAA). Mention EMR/EHR systems (Epic, Cerner). Use clinical terminology relevant to your specialty. Highlight patient outcomes and care metrics.
Lead with ROI metrics, conversion rates, and revenue generated. Mention tools (HubSpot, Salesforce, Google Analytics). Include campaign types and channels. Use concrete campaign outcomes instead of generic claims.
Put education first with GPA if above 3.5. Include relevant coursework, capstone projects, and internships. Highlight transferable skills and leadership roles. Use action verbs even for academic projects.

Many mid-size and large employers use ATS platforms, and smaller employers often use lightweight recruiting tools. Clean formatting and role-specific keywords are useful regardless of the employer size.
Yes, modern ATS systems can parse PDF files. However, PDFs with complex layouts — multi-column designs, tables, text boxes, or embedded images — may not parse correctly, causing sections to be lost or scrambled. Use a single-column, cleanly formatted PDF for best results. Our ATS-optimized templates are designed to be perfectly parseable.
Study the job description for the role you're targeting and identify required skills, certifications, tools, and qualifications. Mirror these keywords naturally in your resume — especially in your skills section, summary, and experience bullet points. Avoid keyword stuffing; ATS systems also check for natural language quality. Our builder's JD Match feature automatically identifies and suggests missing keywords.
