Infrastructure knowledge is increasingly expected of senior backend engineers, not just DevOps specialists. Interviewers want to know that you understand containerization, orchestration trade-offs, and how to design deployment pipelines that don’t cause outages.
These 8 questions cover the infrastructure concepts most relevant to senior interviews: Docker internals, Kubernetes architecture, CI/CD best practices, and cloud-native design patterns. Understanding these helps you bridge the gap between writing code and running it reliably in production.
Focus on understanding concepts deeply enough to explain them in your own words. For each topic, practice articulating the trade-offs and real-world applications — interviewers care about practical judgment, not textbook definitions.
