Choosing between them

Frequently asked questions
Is “improve” a bad word for a resume?
Not bad, but often vague. A more specific word such as enhanced, plus a result, reads stronger.
Can I use these words in a cover letter?
Yes. The same rule applies: be specific and give proof.
Will these words help with an applicant tracking system?
Matching depends mostly on skills and job titles. Strong verbs help the person who reads your resume next.
