In many contexts, a resume is typically limited to one or two pages of size A4 or letter-size, highlighting only those experiences and qualifications that the author considers most relevant to the desired position. Many resumes contain keywords or skills that potential employers are looking for via applicant tracking systems, make heavy use of active verbs, and display content in a flattering manner.
So the exact purpose of a resume is to summarize your experience, knowledge, and accomplishments. Therefore, you must avoid being too wordy. Say exactly what you mean in the least number of words possible. The length of your resume is important. Resumes should be from 1 to 3 pages long. Don't be tempted to make your resume longer than 3 pages, even if you have a lot to tell. Remember, a resume is supposed to be a summary. A resume that is too long simply will bore the reader.
My approach to resume writing involves the use of a skill set based approach and that means when a recruiter or hiring manager opens the resume they first read skill sets that have been acquired throughout the candidate's career. More importantly, the skill sets listed are directly related to the job or career the candidate is interested in. This can change the entire perspective of the candidate when viewed by a potential employer as now they are viewed beyond the current job they hold. This is an especially helpful approach for anyone who is interested in changing jobs or careers.
Many employers now find candidates' resumes through search engines, which makes it more important for candidates to use appropriate keywords when writing a resume. Larger employers use Applicant Tracking Systems to search, filter, and manage high volumes of resumes. Job ads may direct applicants to email a resume to a company or visit its website and submit a resume in an electronic format.
