Free ATS resume checker tailored to developer roles. Paste a job description, upload your CV, get the exact missing keywords with point values, formatting flags, and actionable fixes — in under 60 seconds.
The ATS is dumb on purpose: it parses your CV into plain text and scores keyword overlap with the job description. It does not read between the lines. If your skills are in a fancy box, listed as “K8s” when the JD says “Kubernetes”, or hidden behind a multi-column layout, the ATS does not see them. You get auto-rejected without a single second of human attention.
The ATS extracts raw text from your PDF. Tables, columns, text boxes, and images often break this step entirely.
It scores keyword overlap with the job description: hard skills, soft skills, titles, certifications. Synonyms count less. Exact phrasing wins.
Below a match threshold, your application is auto-rejected or buried. The recruiter never sees it. You get silence or a templated email.
Match percentage between your CV and the target job description, calibrated to recruiter pass thresholds (typically 70+).
Each missing keyword from the JD with its weight ("Kubernetes +11 pts", "GraphQL +9 pts") so you know exactly what to add and where.
Multi-column layouts, embedded images, non-standard headings, fonts that fail OCR — anything that would silently break ATS extraction.
"K8s" vs "Kubernetes", "TS" vs "TypeScript", "JS" vs "JavaScript". The ATS scores exact matches higher. We flag every mismatch.
After the ATS, an HR recruiter scans your CV for an average of 6 seconds looking for red flags. Then a hiring manager evaluates your GitHub, LinkedIn, and seniority signals. RejectCheck audits all three layers in one pass — not just the ATS.
An ATS checker simulates the Applicant Tracking System that recruiters use to filter resumes before a human review. It scores your CV against a job description, surfaces missing keywords, and flags formatting issues that break automated parsing.
Yes. The first analysis on RejectCheck is free, no signup required. You upload your CV and paste the target job description — you get an ATS score with the exact missing keywords and their point values.
Most ATS checkers stop at keyword matching. RejectCheck adds a developer-specific layer: GitHub signal audit, technical skill gap radar, seniority audit, and red-flag detection (vague titles, passive voice, employment gaps). It is built for engineers, not generic candidates.
ATS parsers extract plain text from your CV and look for keyword overlap with the job description. Multi-column layouts, text boxes, images, and creative section headings break parsing. Even strong candidates get filtered out by formatting alone before a recruiter sees them.
An ATS checker only tests the automated filter layer (keyword match, parsing). A resume checker like RejectCheck also evaluates how a human recruiter and a hiring manager will read your CV — tone, seniority signals, GitHub/LinkedIn consistency, and structural red flags.
No signup. No data stored. Tailored to one specific job.
