Infosys DevOps Engineer Interview Questions and Process 2026

Cracking the Infosys DevOps Engineer Interview

As Infosys migrates massive enterprise clients from legacy on-premise servers to the cloud, DevOps Engineers have become critical hires. The interview process is highly technical, focusing on your ability to automate software delivery, manage infrastructure at scale, and troubleshoot deployment failures.

Phase 1: CI/CD and Automation (The Foundation)

Infosys wants engineers who can build pipelines that require zero human intervention.

• Jenkins Mastery: Expect deep questions on Jenkins. "How do you write a declarative pipeline?", "How do you handle secrets/credentials securely in Jenkins?", "Explain how you implement a multi-branch pipeline."
• Git & Version Control: You must understand complex branching strategies (GitFlow) and how to resolve merge conflicts. "Explain the difference between git merge and git rebase."
• Scripting: You will likely be asked to write or explain a short Bash or Python script to automate a routine task, such as backing up a database, checking server health, or parsing a log file.

Phase 2: Containerization and Orchestration

This is where they separate the juniors from the seniors.

• Docker Fundamentals: "Explain the difference between an Image and a Container." You may be asked to write a Dockerfile for a simple Node.js or Java Spring Boot application, optimizing it for size and security.
• Kubernetes (K8s) Deep Dive: If you have 3+ years of experience, K8s is mandatory. Expect questions on Pod lifecycle, Deployments vs. StatefulSets, Services (ClusterIP vs. NodePort vs. LoadBalancer), and how you monitor a K8s cluster (Prometheus/Grafana).

Phase 3: Cloud and Infrastructure as Code (IaC)

Infosys executes massive cloud migrations; you must understand the infrastructure.

• Terraform: "How do you manage state files in Terraform when working in a team?" (Answer: Remote state backends like S3 with DynamoDB locking).
• Cloud Platforms (AWS/Azure): Expect scenario-based questions. "Design a highly available architecture on AWS for a web application." You must understand VPCs, subnets, load balancing, and IAM policies.

Top 3 Technical Questions to Prepare

1. Explain your end-to-end CI/CD pipeline. What tools do you use at each stage (Build, Test, Deploy)?
2. How do you ensure zero-downtime deployments in Kubernetes? (Explain Rolling Updates or Blue-Green deployments).
3. Write a simple Terraform script to provision an EC2 instance (or Azure VM) and a security group.
