How to Evaluate Resume Match Scores Responsibly

What a match score actually measures

A match score compares two pieces of text: your resume and one job description. It reflects how many of the posting’s requirements your resume appears to support, and how well. A score describes how your resume text lines up with the text of one job description. It is not a prediction of what any employer’s system will do, and it does not guarantee an interview.

What it cannot measure

• How a particular employer’s system is configured.
• The quality of your work or how well you interview.
• Whether the posting reflects what the employer really wants.
• Whether your resume is truthful.
• Whether it found every requirement in the posting: the matching step can only score the requirements it identified.

Questions to ask of any tool

• Does it show why: which requirements matched and which did not?
• Does it separate evidence in a bullet from a mention in a list?
• Does it say what it did not check?
• Is it clear what happens to the text you paste in?
• Does it promise outcomes? If so, be wary.

Using a score well

1. Use the breakdown, not the number. The gaps and partial matches are the useful part.
2. Fix writing, not facts. Edit where you have real experience; leave real gaps alone.
3. Stop chasing the number. Past a point, edits that raise a score make a resume worse for a human reader.
4. Check with a person. Ask someone to read the result and tell you if it still sounds like you.

About the free check on this site

JobSealer’s free check shows strong matches, partial matches, gaps and a short summary, and uses the same core matcher as the signed-in tools. It is a comparison of text, and says so. It also has to identify the requirements in a posting before it can match them, and it can miss some, so a high score does not prove that every requirement is covered.

A simple sanity check for any score

Take the same resume and the same job description to two tools. If the numbers differ widely, that is expected: they use different methods. What matters is whether the lists of matched and missing requirements agree on the main points.

Then change one thing, such as adding a real, relevant bullet, and see whether the result moves in the direction you would expect. A score that does not respond sensibly to a real improvement is not telling you much.

Frequently asked questions

Is a score of 80 good?

There is no universal threshold. What counts is whether the central requirements are covered by real evidence.
