What the Match Score Measures

ThreeArrow.ai's score is a product heuristic based on job-description keyword coverage and profile completeness. It is useful for comparison, but it is not a company's proprietary ATS score and cannot predict a hiring outcome.

How to Find Relevant Terms

Paste the job description into ThreeArrow.ai to compare its recurring skills and phrases with your profile. Investigate missing terms, then add only the ones that truthfully apply to you.

Where Terms Belong

Use a skill or tool where it has evidence: in a work bullet, project, certification, or focused skills section. A bare keyword is less useful than a concise example of how you used it.

Acronyms and Full Names

When space permits, introduce a specialized acronym with its full name on first use, such as 'Search Engine Optimization (SEO).' This improves clarity for human readers too.
