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.

Applied Researcher (Product)

Apolloresearch · London

Application deadline: We are conducting interviews actively and aim to fill this role as soon as we find someone suitable.  THE OPPORTUNITY Join our new AGI safety product team and help transform complex AI research into practical tools that reduce risks from AI. As an applied researcher, you'll work closely with our CEO (also Head of Product), product engineers and Evals team software engineers to build tools that make AI agent safety accessible at scale for our customers. Our current focus is the monitoring of AI coding agents for AI safety and security failures. You will join a small team and will have significant ability to shape the team & tech, and have the ability to earn responsibility quickly.  You will like this opportunity if you're passionate about using empirical research to make AI systems safer in practice. You enjoy the challenge of translating theoretical AI risks into concrete detection mechanisms. You thrive on rapid iteration and learning from data. You want your research to directly impact real-world AI safety. KEY RESPONSIBILITIES Research & Development - Systematically collect and catalog coding agent failure modes from real-world instances, public examples, research literature, and theoretical predictions - Design and conduct experiments to test monitor effectiveness across different failure modes and agent behaviors - Build and maintain evaluation frameworks to measure progress on monitoring capabilities - Iterate on monitoring approaches based on empirical results, balancing detection accuracy with computational efficiency - Stay current with research on AI safety, agent failures, and detection methodologies - Stay current with research into coding security and safety vulnerabilities Monitor Design & Optimization - Develop a comprehensive library of monitoring prompts tailored to specific failure modes (e.g., security vulnerabilities, goal misalignment, deceptive behaviors) - Experiment with different reasoning strategies and output formats to improve monitor reliability - Design and test hierarchical monitoring architectures and ensemble approaches - Optimize log pre-processing pipelines to extract relevant signals while minimizing latency and computational costs - Implement and evaluate different scaffolding approaches for monitors, including chain-of-thought reasoning, structured outputs, and multi-step verification Future projects (likely not in the first 6 months) - Fine-tune smaller open-source models to create efficient, specialized monitors for high-volume production environments - Design and build agentic monitoring systems that autonomously investigate logs to identify both known and novel failure modes
