Of course, poor writing style and grammar play the spoil sport and will spill the water on your chances of getting the dream but more than the writing style and grammar, it is "call to action". Defining a call to action is the toughest task a job seeker have to undergo while writing a resume.
Call to action is a generic word, phrase or a term that excites or encourages the reader or the audience to take an action. Usually calls to action are placed or provided after presenting strong set of factual data, accomplishments and achievements in web copies, seminars, content and at websites. Any information without proper "call to action" is termed as incomplete.
Why "Call to Action" "CTA" in Resume:
Usually your resume or a CV is no less than a marketing copy or an informational brochure and in the same scenario the recruiter/hiring manager of an organization can be easily classified as a customer as he is hiring your services for his organization. The recruiter/hiring manager who are responsible to hire you for doing the advertised job have to go through huge piles of resume and they are instructed to find out whether the candidate is suitable for doing the job by looking at the resume. To speed up the process they are trained to read between the lines what the candidate can bring to the job and how much capable he is in doing the job.
How should one include CTA in Resume:
Calls to action are action oriented words which can communicate your capability for the organization and it can be communicate through education, responsibilities, accomplishments and the projects, but CTA can't be effective unless it is placed at the right position and in a right words. In a particular resume candidate can put more than one CTA and can also placed one CTA at different places depending on the organization applying for.
Though it is very difficult to define a CTA for any specific industry/company but one can get it right by researching on the industry and the professionals skills being hired through LinkedIn and apply the same in their CV/Resume.
