There used to be a day when you could create one generic resume and then blast it to a wide range of jobs you were interested in applying to. Even if you are using a resume service this practice of blasting is generally frowned upon. HR professionals are inundated with resumes and they want to see that applicants have read the ad and are responding directly to it. One-for-all type of resumes are easily spotted and are generally discounted by HR. So work with a resume service to see how you can best tailor yours for each job you are applying to.
Remember you resume will be read by humans as well as by machines which will scan for the right keywords. So put some time and energy into your keywords when you write. Resumes must grab the attention of both the human and the computer scanner.
Tailor the resume to the job description Make sure that every time you apply for a job that you adjust your resume to the particular place you are applying. Read through the job description and make notes of any areas being focused on. Make sure to add information to your resume that highlights your abilities in those areas and makes you more attractive for the particular position you are applying for.
