1. Look at the job listing and skills listed. You need to include the exact keywords from the job description to get your resume in front of an actual human. Do you have those skills? Fantastic! Be sure to list them.
2. Include as many relevant hard or technical senior unix systems administrator skills as possible for each job you apply to.
3. Be specific with the skills you have and be sure you are using the most up to date and accurate terms.

These five steps should give you a strong elevator pitch and land you some senior unix systems administrator interviews.

Your work experience should be structured:

2. Job title, along with company name and location on the left.
3. Put the corresponding dates of employment on the left side.
4. Keep only relevant jobs on your work experience.

Remember, your resume is not a list of responsibilities or a job description. This is your chance to show why you're good at your job and what you accomplished.

Use the XYZ formula for your work experience bullet points. Here's how it works:

• Use strong action verbs like Led, Built, or Optimized.
• Follow up with numbers when possible to support your results. How much did performance improve? How much revenue did you drive?
• Wrap it up by explaining the actions you took to achieve the result and how you made an impact.

This creates bullet points that read Achieved X, measured by Y, by doing Z.
