• Performance Testing – Utilizing tools like IxChariot, iPerf, or Octobox to measure throughput, latency, and packet loss.
• Advanced concepts (less common) – DFS (Dynamic Frequency Selection) channel testing, beamforming validation, and mesh network routing protocol analysis.

Example scenarios:

• "Describe how you would test a new Wi-Fi gateway's steering capabilities when a client device moves from a 5GHz band to a 2.4GHz band."
• "You observe high packet loss during a throughput test in a shielded chamber. What variables do you isolate first to identify the root cause?"

Security & Test Automation Engineering

This area evaluates your coding proficiency, framework architecture skills, and ability to embed security checks directly into the software development lifecycle.

Be ready to go over:

• Automation Frameworks – Designing scalable, maintainable frameworks using Selenium, Appium, PyTest, or TestNG.
• CI/CD Integration – Triggering automated suites via Jenkins, GitLab CI, or GitHub Actions.
• Vulnerability Scanning – Utilizing automated tools to scan dependencies and APIs for known security flaws.
• Advanced concepts (less common) – Custom test-listener implementation, parallel grid infrastructure management, and containerized test execution using Docker and Kubernetes.

Example scenarios:

• "How would you design an automated test suite that must run across 50 different physical Android and iOS devices simultaneously?"
• "Explain how you would write an automated test to detect SQL injection vulnerabilities on an exposed client API endpoint."

As a QA Engineer at Inabia Software & Consulting, your daily work will vary depending on your client assignment, but it will consistently center around technical excellence and proactive quality management.
