Poor communication skills and lack of attention to detail will immediately disqualify the majority of job seekers
As a Certified Professional Resume Writer and founder of Haute Resume & Career Service, LLC. I see resumes written by college educated professionals with serious flaws that often highlight either their lack of attention to detail and/or poor written communication skills.
Typos or poorly worded sentences may seem innocuous in themselves but since your resume is supposed to be an example of your best work many hiring managers are unlikely to forgive the mistake. Does this mean that you are unqualified or unable to excel in the position? Absolutely not, but written communication skills are crucial in the work environment. Employers hiring customer-facing employees depend on them to act as an extension of their brand.
Crafting a compelling resume isn't as easy as most people think and certainly isn't a laundry list of tasks from previous jobs. If marketing or written communication skills are not your areas of expertise it is best to hire a professional.
However, should you decide to write your own resume; take the time necessary to study today's resume formats, understand the employer's needs, and double and triple check your resume for errors before applying for the job. The time you invest in your resume will come back again and again in the form of more interviews and higher salary offers.
