+2. Why are you planning to move from your current organization?
+
+3. Can you explain what you are currently doing in your organization?
+
+4. Which cloud platform do you have experience with?
+
+## Behavioral & Situational
+
+1. Suppose you are on an incident call and two teams come to you with two different solutions. As a DevOps engineer, you need to choose only one. How would you manage the situation?
+
+2. Suppose you are conducting a project meeting and two team members strongly disagree with your proposed solution. How would you communicate with them and explain your problem statement and solution?
+
+## Kubernetes
+
+1. Suppose microservices in an EKS cluster are repeatedly restarting and causing intermittent user impact. How would you investigate the issue?
+
+2. How would you design infrastructure on Kubernetes for five micro frontends and 18 APIs with high availability, low latency, and optimized resource utilization?
+
+3. How would you use separate node groups for frontend and backend workloads?
+
+4. How would you expose multiple microservices using an Ingress Controller and an Application Load Balancer?

+2. What are Splunk APM and Splunk RUM?
+
+3. How would you implement full-stack observability using APM and RUM?
+
+4. Suppose user login is intermittently failing. How would you diagnose the issue?
+
+5. What metrics, logs, traces, and application components would you check while troubleshooting intermittent login failures?

+
+3. How does DNS, the Application Load Balancer, Ingress, Kubernetes Service, and Pod work together in the request flow?
+
+## Multi-Region AWS & Disaster Recovery
+
+1. Suppose the same application is deployed in two EKS clusters across two regions, such as US East and US West. How would routing and failover work?
+
+2. How would you configure Route 53 for multi-region traffic routing?
