Research by The Ladders suggests, that on average, applicants’ résumés are accorded six seconds only during the screening stage for talent recruitment. Thus a powerful summary is needed on top of every resume. In order to execute so, a few steps must be taken correct. First of all, the applicant’s area of expertise most relevant to the position must be highlighted. Specific results achieved must be captured. The years of experience must be noted including the organizations and industries worked in. Generic, stale references such as excellent communication skills, result-oriented or team player must be avoided. In the main segment of the resume, one must detail the different areas of expertise one has experience in. Some selected accomplishments must be separately mentioned. These skills mentioned are ideal for resumes, but for LinkedIn a different strategy is needed, as in the latter the space for summarizing is much longer.
