With a strong background in Linux, Python, and Go, and extensive experience troubleshooting complex issues across the open source stack, I am confident in my ability to resolve critical customer problems and contribute to Ubuntu's success. In my previous role, I debugged and fixed issues in Kubernetes and Ceph deployments, collaborating with upstream communities to release patches. My ability to work autonomously and communicate technical details clearly aligns with Canonical's remote-first culture. I am passionate about open source and eager to join a team that values innovation and collaboration. Thank you for considering my application. Sincerely, [Your Name] Copy ### Sample Interview Questions Describe your experience troubleshooting a complex issue in a Linux-based infrastructure. What tools did you use and how did you resolve it?I once debugged a production issue where Ceph OSDs were crashing. I used gdb and strace to analyze core dumps, identified a memory corruption bug in the BlueStore, and provided a workaround while I patched the code and contributed the fix upstream.How do you prioritize multiple critical customer issues? Give an example.I assess severity and impact. For instance, a data loss issue takes precedence over a performance degradation. I communicate timelines to stakeholders and escalate if needed. I also maintain a personal Kanban board to track progress.Explain how you would debug a networking issue in an OpenStack environment.I'd start by checking the neutron logs, then verify network connectivity with ping and traceroute. I'd use tcpdump to capture packets and analyze them with Wireshark, check OVS flows, and review the configuration of security groups and routers.Can you describe a time you contributed to an open source project? What was the process?I contributed a fix to the Kubernetes scheduler for a bug that caused pods to be pending. I forked the repo, wrote a test, submitted a PR, and engaged with maintainers for review. The fix was merged and included in a subsequent release.How do you stay current with rapid changes in open source technologies?I follow release notes and mailing lists for key projects like Ubuntu, Kubernetes, and Ceph. I also experiment with new features in my home lab, attend virtual meetups, and contribute to discussions in online forums.
