Summarize your key strengths/achievements in desktop support using a resume summary
Hiring managers do not have enough time to go through entire resumes. So they mostly skim through in under 8 seconds as they look for the ideal candidate. Therefore, condense your key achievements and strengths in the resume summary where they can’t be missed. Keep it short and precise, 3-4 sentences. Notice how this applicant captures their expertise in Windows OS in the resume summary.
