Here’s what we’re going to cover in this guide:

  • How to properly format your resume for success in 2022 
  • How to talk about your work experience and personal projects
  • How to create a competitive skills section
  • How to customize your resume for each job you apply to

Formatting a Senior System Administrator Resume

Reverse chronological structure: Recent experience first

Reverse chronological resume is the most popular which almost all job seekers should be using. This format means listing out the most recent and relevant things first. It starts with the most recent timeline and you work your way backward, e.g. the latest job position comes first in your work experience section, not the oldest. Structuring your resume this way makes your career timeline more established. 

Senior System Administrator Resume Length

Stick to 1 page.

Most IT Specialists have found that their best shot at landing an offer is by having a one or two-page resume. This includes a collection of sections that cover relevant past experiences. Your resume should be no longer than three pages. The risk of going beyond two pages is including irrelevant content that could distract from your qualifications.

Avoid Common Senior System Administrator Resume Format Mistakes

1) Resumes must include as much content as possible.

2) Uniform and labeled  section headers

When it comes to creating an ATS-optimized resume, it’s good to know how it will be read by the software. Like most human readers, the ATS will read from left to right and top to bottom. 

3) Minimal white-space
