Simulates real production failures across every major tool — structured as incident-response scenarios with investigation steps and solutions:
- AWS: EC2 downtime, RDS failover, EKS node not-ready, Auto Scaling failures
- Kubernetes: Pod CrashLoopBackOff, OOMKilled, pending scheduling, HPA not scaling
- Docker: Container exits, image pull errors, network connectivity issues
- Jenkins: Pipeline failures, agent connectivity, credential errors
- Terraform: State lock conflicts, drift detection, import issues
- Datadog: Alert storms, missing metrics, APM trace gaps
- Prometheus + Grafana: Scrape failures, dashboard gaps, alert routing
- Networking: DNS resolution failures, load balancer health check issues
Based on actual production incidents — not textbook problems. Topics include:
- Kubernetes + ArgoCD sync failures
- Jenkins pipeline flapping
- AWS CloudWatch alarm misconfiguration
- Linux high CPU/memory debugging
- Terraform state corruption recovery
- Docker daemon crashes in CI agents
Simulates how interviewers dig deeper after your initial answers:
- Cross Q&A — what the interviewer asks after you explain your project
- Follow-up Q&A — based on your resume, self-introduction, and project walk-through
- Sanket Chopade-specific — questions tailored to your actual resume and projects
Quick-fire questions for building speed and recall under pressure — ideal for final revision the night before an interview.
Phase 1 — Fundamentals
Q&A-linux.md → Q&A-devops.md → Q&A-aws.md → Q&A-git-github.md → Q&A-jenkins.md
│
Phase 2 — Core Tools
Q&A-docker.md → Q&A-kubernetes.md → Q&A-terraform.md → Q&A-ansible.md
│
Phase 3 — Monitoring
Q&A-cloudwatch-prometheus-grafana-datadog.md → Q&A-monitoring-observability.md
│
Phase 4 — Scenario Practice
production-style-* → real-world-scenario-based-*
│
Phase 5 — Interview Simulation
HR-Interview/ → Follow-Up-QA/ → Cross-QA/ → rapid-fire-mock-interview-Q&A.md
Use these structures in every technical answer:
For conceptual questions:
Definition → How it works → Real example from your project
For troubleshooting questions:
Symptom → Investigation steps → Root cause → Fix → Prevention
For behavioral questions (STAR):
Situation → Task → Action → Result
DevOps pipeline answer template:
Code push → GitHub → CI trigger (Jenkins / GitHub Actions)
→ Build + Test → Docker image build → Push to ECR
→ Deploy to EKS → Monitor with Prometheus + Datadog
Use your editor's global search (Ctrl+Shift+F) or grep to find specific topics:

grep -r "state lock" . # Terraform state issues
grep -r "pipeline failed" . # CI/CD failure scenarios
grep -r "high CPU" . # Linux/EC2 performance issuesSanket Ajay Chopade — DevOps Engineer
