A comprehensive and interesting résumé is best for any IT job.
First, include a three-line summary detailing how many years of IT experience you have (if relevant), including major job achievements. If you have no experience and are applying for an entry-level job, your summary should focus on how you can meet the job objectives outlined in the job post.
Second, list your job experience in chronological format, with the most recent vocational achievements first. This section should be compatible with the requirements and goals laid out in the job ad. If you have no IT job experience, note relevant side projects, Help Desk jobs, system administrative tasks, freelance projects, and volunteer work.
Third, mention system administrator skills. Include both soft and hard skills here.
Fourth, list your degree and/or IT certifications. Only include your exam scores if they are high and your résumé is on the thin side.
Lastly, include any IT-related conferences you attended or presented at, publications, awards, and additional activities.
