Focus on scenarios where you demonstrated teamwork, problem-solving, and adaptability, particularly in remote settings.

7. Prepare for Troubleshooting Scenarios

Practice diagnosing and resolving common issues in GitLab, such as:
- Failed CI/CD pipelines.
- Misconfigured GitLab Runners.
- Merge conflicts or access issues.

8. Mock Interviews and Feedback

Conduct mock interviews with peers or mentors to simulate the actual interview environment.
Seek constructive feedback to refine your technical answers and communication skills.

9. Be Ready for Take-Home Assignments

If given a take-home project, plan your time effectively and follow GitLab's best practices.
Write clean, well-documented code and provide a clear explanation of your solution.

10. Ask Questions
