The score is job-specific
A strong score for one role can be weak for another. The same resume may match a backend engineering role well and a product-focused role poorly because the required skills, tools, and responsibilities differ.
What usually affects the score
- Required skills and technologies from the job description.
- Repeated responsibilities such as migration, automation, stakeholder communication, or support.
- Seniority cues, domain language, and role-specific outcomes.
- Whether your strongest bullets contain the most important requirements.
What the score does not measure
It does not know if you will interview well, whether a recruiter likes your background, or whether a requirement is truly mandatory. It is one input. Use it to find gaps, then keep the final resume accurate and readable.
How to use it well
Treat the score as a diagnostic. If it is low, add missing relevant terms only when they are true to your experience. If it is high but the resume sounds generic, improve the bullets so they show specific outcomes.
