FAQ

Questions about the ATS Resume Checker

How is the ATS keyword match score calculated?

The tool picks known tech skills and the most frequent terms from the job description, then checks which of them appear in your resume. The score is the share of those target keywords found, out of 100.

What ATS red flags does the checker look for?

It checks for an email and phone number, standard section headings like Experience and Skills, a word count between 250 and 1100, lines with numbers, fancy symbols, column-style spacing and heavy use of I, me and my.

Should I add every missing keyword to my resume?

No. Only add keywords for skills you really have, since recruiters will ask about them in interviews. Click any missing chip to copy it.

Is the ATS Resume Checker free and private?

Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
