• System Automation – Automating routine operational tasks like backups, user management, or service restarts.
• Advanced concepts (less common) – Multi-threading/multiprocessing in Python, writing custom Kubernetes operators.

Example questions or scenarios:

• "Write a Python script to parse an Apache access log and return the top 10 IP addresses with the most requests."
• "Create a script that checks the health of a list of endpoints and alerts if any return a 5xx status code."
• "How would you automate the rotation of secrets across hundreds of servers?"

Containerization and Orchestration

Modern infrastructure relies heavily on containers. At Yelp, Docker and Kubernetes are central to our deployment strategy. We evaluate your hands-on experience with building efficient images, managing container lifecycles, and orchestrating complex microservices architectures.

Be ready to go over:

• Docker Fundamentals – Writing optimized Dockerfiles, managing image layers, and understanding container isolation.
• Kubernetes Architecture – Knowledge of control plane components, Pods, Deployments, and Services.
• Cluster Networking – Understanding Ingress controllers, service meshes, and pod-to-pod communication.
• Advanced concepts (less common) – Helm chart creation, custom resource definitions (CRDs), and cluster autoscaling strategies.

Example questions or scenarios:

• "Explain the difference between a Deployment and a StatefulSet in Kubernetes."
• "A pod is stuck in a CrashLoopBackOff state. Walk me through your troubleshooting steps."
• "How do you optimize a Dockerfile to reduce image size and build time?"

System Design and Reliability

As you progress to the onsite rounds, you will face system design questions. We want to see how you architect scalable, highly available systems. Strong candidates will proactively discuss trade-offs, single points of failure, and observability.

Be ready to go over:

• Load Balancing – Distributing traffic efficiently across multiple regions or availability zones.
• Data Storage – Choosing the right database for the job and understanding replication and partitioning.
• Observability – Designing systems with metrics, logging, and tracing built in from the start.
• Advanced concepts (less common) – Chaos engineering, disaster recovery planning, and multi-region active-active architectures.

Example questions or scenarios:

• "Design a scalable image hosting service for user reviews on Yelp."
• "How would you architect a CI/CD pipeline for a microservice that deploys 50 times a day?"
• "What metrics would you monitor to ensure the reliability of a distributed caching layer?"

As a DevOps Engineer at Yelp, your day-to-day work will be highly dynamic, bridging the gap between software development and systems administration. You will spend a significant portion of your time designing and maintaining the CI/CD pipelines that allow our engineering teams to deploy code rapidly and reliably.
