Employers will scan a résumé for about 30 seconds to decide whether to consider an applicant. Some may use an automated scan in order to short list résumés. Get your résumé in the ‘for consideration’ pile.
A résumé is a "snapshot" of you and needs to be:
Written with the employer’s interests in mind
Professional in appearance
Targeted for a particular job or organization
"Letter-perfect." Spelling and grammar mistakes can mean an automatic trip to the reject pile
An honest and clear demonstration of your skills, abilities and achievements
A clear indication of what you offer to the employer
