DevOps Interview Roadmap: Kubernetes + Terraform in 30 Days
A practical month-long plan to prepare for high-signal DevOps interviews focused on Kubernetes and Terraform.
Week 1: Foundations and language
Start by reviewing Kubernetes primitives and Terraform state behavior. Most candidates fail because they memorize commands but cannot explain trade-offs under pressure.
Create a one-page glossary in your own words: rollout, drift, immutable infra, idempotency, blast radius, and rollback. This becomes your interview language anchor.
Week 2: Troubleshooting scenarios
Run daily scenario drills: failed deployment, pending pods, unhealthy probes, and state lock conflicts. Keep each drill to 10-15 minutes and always finish with a root-cause note.
In interviews, structured thinking beats speed. Use a triage order: impact, scope, recent change, telemetry, mitigation, prevention.
Week 3: Architecture and trade-offs
Prepare answers for design prompts: multi-env IaC strategy, secret management, and CI/CD controls. Interviewers reward clear constraints over generic best-practice lists.
Explain why you choose one path and what you give up. Trade-off clarity is usually the strongest hiring signal.
Week 4: Simulation and refinement
Do full-length mocks with realistic time pressure and cross-question continuity. Capture weak areas and loop them into daily drills.
If you need realistic mock interviews and quality feedback loops, practice directly on InterviewMind with role-specific challenges and progress tracking.
