What is an ATS Resume Checker?

An ATS Resume Checker is a tool that analyzes your resume against a specific job description and returns a keyword match score. 98.4% of Fortune 500 companies use Applicant Tracking Systems to rank candidates before a recruiter reviews them (Jobscan, 2024 ATS Usage Report). 22skills performs this check in under 30 seconds using GPT-4o-mini, with Claude Sonnet 4.5 as a fallback, and returns a 0-100% score plus a prioritized list of missing keywords.

Is the ATS Resume Checker free?

Yes. 22skills provides 1 free ATS scan with no signup and no credit card required. Creating a free account increases the limit to 5 scans per month. Pro is $14.99/month (or $39/quarter) and includes unlimited scans and AI-powered resume rewriting. Jobscan, the most common alternative, starts at $49.95/month for similar scan volume.

What ATS score do I need to pass?

Aim for 70% or higher to clear most automated ATS filters. For senior roles or positions with heavy application volume, target 80% or above. These thresholds reflect how 22skills weights keyword presence, placement, and frequency — a score below 55% typically means the resume is missing multiple required skills from the job description.

How does 22skills' keyword matching work?

22skills matches keywords using two methods: exact matching (case-insensitive) and fuzzy matching with Levenshtein distance of 2 or fewer character edits. This means "Javascript" and "JavaScript" match, as do common abbreviations and misspellings. The keyword dictionary contains 500+ ATS keywords organized by category, each with synonyms and variations. Keywords appearing in the job description as required qualifications are weighted more heavily than those appearing in the nice-to-have section.

How does 22skills compare to running the check manually through ChatGPT?

Running a resume check through ChatGPT manually requires: copying the job description, copying the resume, writing a prompt, reading unstructured output, and iterating. The process is open-ended, produces no consistent score, and does not track changes across applications. 22skills runs the same underlying AI models but wraps them in a structured pipeline that returns a 0-100% score, a matched keyword list, a missing keyword list, and prioritized suggestions — all in under 30 seconds. It also stores analysis history so you can track score changes across resume versions.

Why do resumes get rejected by ATS?

The most common ATS rejection reasons are: missing keywords that match the job description, complex formatting that ATS parsers cannot read (tables, text boxes, multi-column layouts, graphics), non-standard section headers, and critical keywords spelled differently than the job description uses. With 250+ applications per corporate job opening on average (Glassdoor), ATS filters make these mismatches decisive. 22skills identifies all these issues in one scan.

What is the best free ATS resume checker?

The best free ATS resume checker scores your resume against a specific job description rather than giving a generic format grade. 22skills returns a real job-targeted ATS match score (0-100%), your matched and missing keywords, and prioritized fixes on the free tier: 1 scan with no signup, or 5 scans per month with a free account. Many alternatives label themselves free but only show a generic format score or gate the job-targeted analysis behind a paid plan (Jobscan from $49.95/month, Resume Worded Pro $49/month). 22skills keeps the job-description match — the part that actually predicts whether you pass the ATS filter — free.

Are free ATS checkers accurate?

Accuracy depends on whether the tool compares your resume to the actual job description. A free checker that only grades formatting misses the main reason resumes get filtered out: missing keywords from the specific posting. 22skills runs the same AI models on the free tier as on Pro (GPT-4o-mini primary, Claude Sonnet 4.5 fallback) and matches against 500+ ATS keywords using exact and fuzzy matching, so a free scan uses the same scoring engine as a paid scan. The only difference is volume: 1 free scan, 5 per month with a free account, or unlimited on Pro at $14.99/month.

atsCheckerRole.roles.software-engineer.shortTitle ATS Resume Checker FAQ

What keywords do ATS systems look for in a software engineer resume?

ATS systems scan software engineer resumes for programming languages (Python, Java, JavaScript, TypeScript, C++), frameworks (React, Angular, Node.js, Spring Boot, Django), databases (PostgreSQL, MongoDB, Redis), cloud platforms (AWS, Azure, GCP), DevOps tools (Docker, Kubernetes, CI/CD), and methodologies (Agile, Scrum). The exact keywords depend on the job description — use an ATS checker to match your resume to each specific role.

How do FAANG and startup ATS differ for software engineers?

FAANG companies (Meta, Amazon, Apple, Netflix, Google) typically use custom or heavily configured ATS systems that weigh specific tech stack keywords heavily — listing "distributed systems" and "system design" matters more for senior roles. Startups often use simpler ATS like Lever or Greenhouse and filter more broadly. In both cases, matching the exact technologies from the job description is critical. FAANG postings tend to list fewer but more specific requirements, while startups may list broader technology categories.

Should I list every programming language I know on my resume?

No. Only list languages and tools mentioned in the job description, plus closely related technologies. ATS systems match your resume against the specific job posting. Including irrelevant technologies dilutes your keyword density and can lower your ATS score. Tailor your resume for each application.

How do I format a software engineer resume for ATS?

Use a clean, single-column layout with standard section headings (Experience, Education, Skills). Avoid tables, graphics, and multi-column layouts that ATS cannot parse. List technologies in a dedicated Skills section AND within your experience descriptions. Use both acronyms and full names (e.g., "Amazon Web Services (AWS)").
