Highlight certifications, lab experience, and projects. Use action verbs and quantify achievements where possible.

Practice Scenarios

Be ready for scenario-based questions. Interviewers want to know how you think through problems, not just if you know the answer.

Hands-on experience is the best interview prep. Use your course labs to build real configurations you can speak to confidently.
