Recruiters often spend less than a minute on the first scan of a resume. Lead with a two-line summary of what you do and the results you have delivered. Use the exact job title you are targeting, list skills that appear in the job description, and quantify achievements wherever you can (for example “reduced report preparation time by 40%”). Keep it to one or two pages, use a clean single-column layout so applicant tracking systems can read it, and save it as PDF unless the employer asks otherwise.
