When writing their resume, IT professionals will often rely on the advice they read for nontechnical resumes, advice that doesn’t necessarily relate to their circumstances. One case in point relates to the length of their resume. For IT professionals, it’s often not realistic to limit a resume to 2 pages.
Technical Detail: Your resume needs to appeal to both HR managers and technical hiring managers. For HR, you should include what you did and why you did it. For technical hiring managers, you should include how you did the work, and the technical processes that you used.
Certifications and Professional Development: There are few industries where ongoing certifications and professional development are as crucial.
Technology Profile: Hiring managers want to know with which technologies you have current skills and recent experience. Even if you remove the old technologies, most IT professionals still have a long list of tools, processes, and methodologies to include.
Career Directors International , a noted career association, found that 3 pages are fine as long as the content is valid. If the reader likes what they read on page 1, they’ll move on page 2, and so on. You may irritate a small minority of resume readers but you can’t make everyone happy. Furthermore, applicant tracking systems don’t care about the length of your resume.
