Key Takeaways

  • 75% of U.S. employers use automated applicant tracking systems to screen resumes before a human reviews them (Harvard Business School & Accenture, 2021)
  • The most common ATS failures are missing keywords, incompatible formatting, and incorrect file types
  • ResumeGeni scores your resume across 8 parsing layers — modeled on the same steps enterprise ATS platforms like Workday, Greenhouse, and Taleo use to evaluate candidates

How ATS Resume Scoring Works

Applicant tracking systems parse your resume into structured data — extracting your name, contact info, work history, skills, and education — then score how well that data matches the job requirements. Many ATS rejections happen because the parser couldn't extract critical fields, not because the candidate wasn't qualified.

LayerWhat It ChecksWhy It Matters
Document extractionFile format, encoding, readabilityCorrupted or image-only PDFs fail immediately
Layout analysisTables, columns, headers, footersMulti-column layouts break field extraction
Section detectionExperience, education, skills headingsNon-standard headings cause sections to be missed
Field mappingName, email, phone, dates, titlesMissing contact info is a common cause of immediate rejection
Keyword matchingJob-specific terms, skills, certificationsKeyword overlap affects recruiter search visibility and ATS scoring
Chronology checkDate ordering, gap detectionReverse-chronological order is expected by most ATS
QuantificationMetrics, numbers, measurable outcomesQuantified achievements help human reviewers and some scoring models
Confidence scoringOverall parse quality and completenessLow-confidence parses get deprioritized in results

Frequently Asked Questions

Is ResumeGeni free?
Yes. ResumeGeni is currently in beta — ATS analysis, scoring, and initial improvement suggestions are free with no signup required. Full guidance and saved reports may require a free account.
What file formats are supported?
PDF, DOCX, DOC, TXT, RTF, ODT, and Apple Pages. PDF and DOCX are recommended for best ATS compatibility.
How is the ATS score calculated?
Your resume is processed through an 8-layer parsing pipeline that extracts structured data the same way enterprise ATS platforms do. The score reflects how completely and accurately your resume can be parsed, plus how well your content matches common ATS ranking criteria.
Can ATS read PDF resumes?
Yes, but not all PDFs are equal. Text-based PDFs parse well. Image-only PDFs (scanned documents) and PDFs with complex tables or multi-column layouts often fail ATS parsing. Our analyzer will flag these issues.
How do I improve my ATS score?
Focus on three areas: use a clean single-column format, include keywords from the job description naturally in your experience bullets, and ensure all sections (contact, experience, education, skills) use standard headings.

Fall Legal Intern

Sierraclub · Washington, DC

Job Title: Fall Legal Intern 
Department: Environmental Law Program
Location: Washington, DC
Reports to: Manager, Environmental Law Program
Duration: 14 weeks, 20 hours per week

Context: At the Sierra Club, we believe in the power of interdependence. Together, we remain committed to the fight for a healthy climate built on a foundation of environmental, racial, economic, and gender justice – a future where all people benefit from a healthy, thriving planet and a direct connection to nature. As the climate crisis and deeply entrenched systemic racism all fuel injustice, we will continue to fight for a bold, transformational agenda that recognizes the interconnectedness between our planet, our humanity, and our future. By recognizing that our destinies are tied, we continue to name that all things are fundamentally connected, and the overlap between ecology, race, gender, and representative government will move to either advance our collective humanity or to oppress it. Sierra Club has close to 800 staff across the country and a network of 64 local chapters that are led and fueled by thousands of volunteers. We are also proud to be a unionized employer, with three labor unions representing more than half of our employees. 

Scope: The Environmental Law Program is at the cutting edge of climate change litigation. We work with our allies to reduce the environmental and public health degradation that flows from the lifecycle of fossil fuel use, ranging from destructive mining and fracking to combustion to disposal. At the same time, we advocate for the expansion of energy efficiency and renewable energy solutions. In the past few years alone, we have achieved tremendous public health and climate change benefits for many communities, including for those engaged in environmental justice struggles in particular. 

ELP seeks law students passionate about public interest environmental litigation to assist with our strategic lawsuits. Interns work on many aspects of litigation, including undertaking legal research, preparing written memoranda, and conducting factual investigation. During the course of the program, students typically work with several of the Club’s attorneys, thus gaining exposure to a wide range of litigation styles. Our interns are encouraged to participate in weekly legal team meetings where we discuss our dockets and strategies.
