• Infrastructure as Code – Structuring Terraform states, managing secrets, and handling infrastructure drift.
• Networking – Subnetting, routing, security groups, and VPN/VPC peering.
• Advanced concepts (less common) – Multi-region active-active deployments, AWS Transit Gateway, and custom Terraform providers.

Example questions or scenarios:

• "Design a highly available infrastructure for a new microservice handling real-time location data. How do you ensure it survives an availability zone failure?"
• "Walk me through how you would structure a Terraform repository for a team of 50 engineers to prevent state conflicts."
• "Explain how you would secure an internal API that should only be accessible by specific backend services."

Containerization and Orchestration

Because Lyft operates a massive microservices architecture, container orchestration is a critical pillar of your day-to-day work. Interviewers will test your depth with Kubernetes, Docker, and service mesh technologies. A strong candidate goes beyond basic kubectl commands and understands the underlying control plane, networking, and scheduling mechanics.

Be ready to go over:

• Kubernetes Architecture – Understanding the API server, etcd, kubelet, and controller managers.
• Workload Management – Deployments, StatefulSets, DaemonSets, and horizontal pod autoscaling (HPA).
• Service Mesh and Networking – How Envoy operates, ingress controllers, and network policies.
• Advanced concepts (less common) – Writing custom Kubernetes operators, eBPF for observability, and managing etcd clusters.

Example questions or scenarios:

• "A pod is stuck in a CrashLoopBackOff state. Walk me through your exact debugging steps."
• "How would you design a deployment strategy to ensure zero-downtime updates for a critical payment service?"
• "Explain how a request routes from an external user, through an ingress controller, and into a specific container."

Continuous Integration and Continuous Deployment (CI/CD)

Developer velocity is a top priority at Lyft. This area evaluates your ability to build, maintain, and optimize the pipelines that deliver code to production. Interviewers look for candidates who can design secure, fast, and scalable CI/CD workflows while implementing proper testing and rollback mechanisms.

Be ready to go over:

• Pipeline Design – Structuring multi-stage builds, caching dependencies, and managing artifacts.
• Deployment Strategies – Blue/green deployments, canary releases, and feature flagging.
• Tooling – Proficiency with tools like GitHub Actions, Jenkins, or ArgoCD.
• Advanced concepts (less common) – Supply chain security, SLSA frameworks, and dynamic environment provisioning.

Example questions or scenarios:

• "Our build times have increased from 5 minutes to 45 minutes. How would you investigate and optimize this pipeline?"
• "Design a CI/CD pipeline that automatically rolls back a deployment if error rates spike in production."
• "How do you handle database schema migrations in an automated CI/CD environment without causing downtime?"

Scripting and Automation

DevOps engineers at Lyft are expected to write code. This is not a pure software engineering interview, but you must be able to automate tasks, parse data, and interact with APIs programmatically. Strong candidates write clean, modular scripts and handle edge cases gracefully.

Be ready to go over:

• Data Parsing – Reading and manipulating JSON, YAML, or log files.
• API Interaction – Writing scripts to query REST APIs, handle pagination, and manage rate limits.
• System Automation – Automating routine Linux tasks, backups, or user management.
• Advanced concepts (less common) – Concurrency/multithreading in automation scripts, building internal CLI tools.

Example questions or scenarios:

• "Write a Python script to parse a large Nginx log file and output the top 10 IP addresses with the most 5xx errors."
• "Create a script that queries the AWS API to find and tag all unattached EBS volumes."
• "Write a function to check the health of a list of URLs concurrently and report any failures."

As a DevOps Engineer at Lyft, your primary responsibility is to ensure the underlying platform is robust, scalable, and easy for product engineers to use. You will spend a significant portion of your time writing and reviewing Terraform code to provision infrastructure, ensuring that all changes are version-controlled, tested, and automated. You will manage the lifecycle of Kubernetes clusters, tuning them for performance and cost-efficiency as traffic patterns fluctuate throughout the day.

Collaboration is a massive part of the day-to-day work. You will embed with or closely support product engineering teams, acting as a subject matter expert on system architecture and deployment strategies. When a team wants to launch a new microservice, you will guide them on best practices for containerization, observability, and capacity planning. You will also build internal tooling and self-service portals that abstract away infrastructure complexity, allowing developers to ship features faster.

Incident response and reliability engineering are also core components of the role. You will participate in an on-call rotation, responding to high-severity alerts. When systems fail, you will lead the troubleshooting effort, diving deep into Linux internals, network traffic, and application logs. After an incident, you will drive the blameless post-mortem process, identifying root causes and implementing automated safeguards to prevent recurrence.

To thrive as a DevOps Engineer at Lyft, you need a solid foundation in both software engineering and systems administration. The ideal candidate brings a proven track record of managing large-scale, highly available environments and possesses a deep curiosity for how complex systems interact.
