Recruiters often rely on software to scan resumes for certain keywords, which is why it’s important for candidates to visually scan their resume before submitting it. I suggest taking a few minutes before submitting your next resume to do this short exercise: read the job description one more time and take note of the skills required, educational degree, specific licenses or other certifications or qualification that are mentioned. Those are all keywords. Now look at your resume and highlight those keywords. If they’re missing, but can be added, do so. Sometimes it’s appropriate to list them, such as in a “core competency” section and other times it’s better to incorporate them in the body of your resume.
