About this tool
An Applicant Tracking System (ATS) is software that recruiters and companies use to filter resumes before a human ever sees them. ATS software scans your resume for keywords and phrases pulled directly from the job description, and resumes with poor keyword overlap are often rejected automatically. The ZorbTool ATS Score Checker compares your resume against any job description and gives you an instant compatibility score, plus a clear list of keywords you matched and the important ones you are missing. Upload your resume as a PDF or Word document, or paste plain text — everything runs locally in your browser. Your resume is never uploaded, stored, or sent to any server. Use it to tailor every application: upload your CV, paste the job posting, and update your resume with the suggested keywords and example sentences. A higher keyword match dramatically improves your chances of landing an interview.
What is an ATS and How Does it Work?
An Applicant Tracking System (ATS) is software that companies use to receive, organize, and filter the resumes they get for every job opening. Over 95% of large employers and most mid-sized companies route every incoming application through an ATS before a human recruiter ever sees it. Popular systems include Workday, Greenhouse, Lever, Taleo, iCIMS and SmartRecruiters. Whether you're applying to a Fortune 500 or a fast-growing startup, your resume is almost certainly being scored by software first.
When you submit a resume, the ATS parses the file, extracts your work history and skills, and then matches them against the job description. Recruiters typically search and rank candidates by keywords pulled from the requisition — job titles, technologies, certifications, degrees and specific skills. Resumes that contain the right terms in the right context rise to the top of the recruiter's queue; those that don't can sit unread.
This is why keyword matching has become the single most important factor in modern resume strategy. Even highly qualified candidates get filtered out when their resumes describe the same skills with different vocabulary than the job posting uses. If the JD says 'project management' and your resume says 'led initiatives', the ATS may not connect the two.
Job descriptions usually combine two types of keywords. Hard skills are concrete, verifiable abilities — Python, SQL, AWS, financial modeling, CPA, GDPR. Soft skills are interpersonal qualities — leadership, communication, problem-solving, collaboration. A strong resume includes both, woven naturally into accomplishment-driven bullet points rather than dumped into a skills list.
The most reliable way to beat the ATS is to tailor your resume for every application. Read the job description, identify the 10–20 highest-priority keywords, and make sure each appears at least once in your resume — ideally in the context of an achievement. Common mistakes to avoid: using images or unusual fonts the parser can't read, stuffing keywords in white text, relying entirely on a generic resume for every job, and burying critical skills in dense paragraphs the ATS may truncate.
