Sample answer
“At my internship with a local ISP, our team faced a significant slowdown in network speed for several clients. I began by checking router logs and running ping tests to identify packet loss. After isolating the problem to a misconfigured switch, I collaborated with a senior engineer to reconfigure it. We restored normal service, and I documented the changes to strengthen our troubleshooting guide for future incidents. This experience taught me the importance of systematic diagnosis and effective communication.”
