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.

Senior Backend Engineer

Replo · San Francisco

About the role

Hiring a senior backend engineer to join our team and focus on system architecture our most popular products.


Things you'll be working on

Architecting and implementing backend systems in Typescript/Node is the core of what you’ll be doing. Real examples include —

  • Designing and building an ingestion pipeline for our analytics/insights products (> 99.99% uptime on Kafka, Clickhouse, Redis)

  • Spiking on our CI/CD to improve stability

  • Build out durable/distributed cart/hosting for our ecommerce product

  • Deploying a multi-tenant NextJS app for shops in Cloudflare

  • Mentoring junior engineers on best-practices

Looking for someone who

  • Can be in office 3-4 days/week in San Francisco

  • Has deep knowledge in distributed systems and SOA — load balancers, databases, queuing, caching, HTTP, APIs, high-availability, fault tolerance, redundancy, at-least-two-of-everything

  • Down to do full-stack work (including frontend even if it's not your main role)

  • Is ALWAYS SHIPPING. We don't spend weeks planning features at Replo

  • Has 4+ years of professional experience with production distributed systems, service oriented architecture

  • Proficient in Typescript. If you have experience writing these systems in Python/Go/Java that’s cool too, as long as you’re willing to learn Typescript/Node — the learning curve on writing TS isn’t that high for high-caliber engineers. Experience or working knowledge of React is great too, but we can teach you that if we need to

  • Has a product and customer-focused mindset

  • Has experience being burned by deployment and maintenance issues. If you have a a strong opinion on how backend systems should be built, that’s good

  • Values writing clean, maintainable software, including documentation (e.g. the code needs to be correct and run fast, but we’re the ones that have to read it and understand it)

  • Is comfortable with ambiguity and defining software architecture patterns to solve customer pain points

Bonus points if you

  • Have started a company before

  • Enjoy attending hackathons

  • Worked at an early-stage (Series A or earlier) startup previously

  • Have not wasted hours interview-prepping on Leetcode

  • Have an eye for visual design (or past experience in product design, Figma, etc)
