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.

Software Engineer, Execution

Circleci · Toronto, Ontario

About The Role

CircleCI is seeking a Software Engineer passionate about maintaining and crafting the future of services that power the heart of our product. You’ll work across a deep slice of our system on features and capabilities ranging from:

  • Orchestrating and scheduling jobs.
  • Introducing new execution environments across our platforms: Docker (Nomad), EC2 and GCP.
  • Maintaining and enhancing the runtime environments, reusable configurations, and integrations that customers rely on.
  • Keeping our large multi-tenant, multi-platform fleet of build servers, distributed cloud infrastructure and generally instrumenting our environments to be running reliably and securely.
  • Help craft the end user testing environments we offer to our customers.
  • Debugging complex issues across the platforms we support.
  • Storing customers caches, artifacts, test results and step output.

About the Team

The Execution team, embedded within the Foundations division, is tasked with ensuring that any job that has permission to run on our platform can be run immediately, reliably, with the appropriate resources and then handle the results from said job.

What You’ll Do:

  • Improve and automate legacy build processes for machine images, convenience images, and certified orbs.
  • Design and build new features, simplify existing services, automate and scale our systems as we continue to rapidly grow and evolve.
  • Write sustainable, testable, high-quality, high-performance code.
  • Support, maintain, and debug production microservices in a highly complex distributed system.
  • Champion a culture of observability and monitoring by using operational data to help your team improve the stability and performance of our systems.
  • Partner with members of a cross-functional team and other partners to set the direction of our platform and product: learn about our business problems, explore solutions through rapid iteration and design exploration, weigh design tradeoffs, and prioritize them to deliver maximum value in a sustainable, incremental fashion.

What You’ll Bring:

  • 3-5 years as a professional developer with experience building reliable, zero-downtime, observable distributed systems using Go, our primary programming language. You'll also encounter bash, JavaScript, and Clojure - all deployed into Kubernetes and as agents on our compute fleet.
  • You write code that’s easily readable, testable, maintainable, and documented. You also have familiarity with observability tools like Honeycomb, Datadog, and Rollbar, and understand how to use that information to address problems in production.
  • Experience using AI-assisted development workflows to accelerate iteration, explore design and SDK interfaces, and debug complex systems, while keeping a commitment to correctness, performance, and long-term maintainability.
  • Experience with Packer, Ansible, and other DevOps tools and workflows.
  • Experience working in open-source projects and interacting with customers through bug reports and pull requests.

We’re Particularly Interested In These Work Styles:

  • Working transparently and collaboratively within a distributed team.
  • Favor toward regular, incremental delivery over precision.
  • Striving for continuous learning and improvement for yourself and your team.
  • Passionate about ensuring that all of our systems—software and human—scale smoothly.
