DevOps / SRE Roadmap

DevOps/SRE interviews evaluate whether you can keep systems healthy under change: automation, reliability, and incident leadership.

Core competencies

• Linux + networking fundamentals
• containers and Kubernetes basics
• observability (metrics/logs/traces)
• CI/CD, safe rollouts, IaC
• incident response and postmortems

10-week plan

Weeks 1–2: Systems fundamentals

• networking + Linux debugging drills

Weeks 3–5: Containers + Kubernetes

• understand core primitives and failure modes

Weeks 6–7: CI/CD + deployment safety

• blue/green, canary, feature flags

Weeks 8–10: Incidents and reliability

• practice incident scenarios and communication

Interview failure modes

• tool trivia without fundamentals
• no mental model for debugging
• ignoring SLOs, saturation, and feedback loops

Archetype adjustments

• FAANG/high-growth: large fleets and standardized SRE practices.
• Enterprise: heterogeneous systems, compliance, slower change windows.
• Automotive/industrial: safety and long-lived systems; higher emphasis on risk control.
