Likely your resume needs to be refreshed and polished up a bit. Here are five things to consider from business and finance writer, Maurie Backman, before you even get started:
Updating your resume takes time - more than the half hour you think it'll take
Include others to ensure it's spot on (an old colleague, perhaps)
Get a second set of eyes to review for errors and consistency
Your resume will determine whether you land an interview; it must be "just so"
Every three months, update your resume. It'll give you peace of mind
Not sure how to fix an outdated resume?
Ditch the "Objective"
Use a professional summary, an overview of your career highlighting skills that differentiate you from other candidates, including keywords from the job advertisement
Regurgitate keywords (within reason) from job advertisements back onto your resume and cover letter
Don't date your education (unless you're a recent grad with no relevant experience). Dates can cause age discrimination
Including all jobs is unnecessary (typically you'll list relevant past positions from the last 15 years)
Go ahead and split job experiences on your resume (one section for sales experience, one section for teaching experience, for example). If you're after a job in sales, place the sales section at the top of the work history section
Omit personal information, like hobbies, number of children or marital status. The modern resume is strictly professional
