Sharing a part of article from KSAT.com.

Many job-seekers have a strategy of producing one generic resume and cover letter and sending it out to dozens, if not hundreds, of companies that are hiring.

While there are some parts of a resume that are OK to remain generic, Martin said it’s important for job-seekers to put in the work and make their resumes stand out by personalizing aspects of their applications.

“There’s a six-second scan rule,” Martin said. “Recruiters, they will glance at your resume for about six seconds. They are looking for certain keywords, skills or expertise. If they don’t see it in the first six seconds, they might not continue reading the resume. You want to tailor your resume.”
