How does the ATS keyword matching algorithm work?

The tool tokenizes the job description to identify high-frequency skills, tools, and qualifications, then calculates the percentage of those terms present in your resume text.

Does a high ATS score guarantee an interview?

No. While high ATS keyword alignment ensures your resume passes initial automated filters, human hiring managers make the final hiring decisions based on qualitative experience and culture fit.

What formatting mistakes cause resumes to fail ATS parsing?

Common causes include multi-column tables, text placed inside header/footer bands, embedded raster images, non-standard section titles, and unsupported file formats.

Is it safe to paste my confidential resume into this checker?

Yes. NexLove processes all text 100% locally in your browser session. No data is sent over the network or saved to any database.

Can I test multiple different job descriptions?

Yes. You can paste and compare against as many different job postings as you need to tailor your resume for specific applications.

What is the recommended keyword match percentage for ATS screening?

Aim for a 70% to 85% keyword match between your resume and the target job description. Avoid 100% exact stuffing, as human recruiters review the parsed document after automated filtering and prioritize natural, context-rich experience.

How does the ATS checker handle hard skills versus soft skills?

The algorithm categorizes keywords into hard technical proficiencies (e.g., Python, Salesforce, SEO, Financial Modeling) and essential soft skills (e.g., Leadership, Cross-functional Collaboration), providing separate match scores so you can balance your profile.
