I applied online. The process took 1 day. I interviewed at SES (Coimbatore) in Jan 2025
Interview
The interview process was well-structured and focused on real-world DevOps challenges. Topics included Docker container security best practices, Kubernetes taints and node draining, service mesh fundamentals, and troubleshooting TCP timeout issues between VMs. The interviewer emphasized both theoretical understanding and hands-on implementation skills, asking how to apply solutions in production-like environments. It was a detailed and technical assessment overall.
Interview questions [1]
Question 1
What are the security best practices to follow when working with Docker containers?
In Kubernetes, how are draining and taints used?
What does "draining a node" mean and when do you use it?
Can you explain what a service mesh is in the context of Kubernetes?
Scenario-based question:
You have two VMs communicating via REST API — VM1 is the client and VM2 is the server. The client is receiving a TCP timeout error when trying to connect to the server. How would you troubleshoot and resolve this?
