Technical Questions

Walk me through how you would design a highly available microservices architecture on AWS or GCP that spans multiple regions. What services would you use, and how would you handle data consistency and failover?

Why they ask this:* Assesses understanding of cloud architecture patterns, multi-region deployment strategies, and ability to make trade-offs between availability, consistency, and cost at a mid-level scope.

Explain the differences between containerization (Docker) and orchestration (Kubernetes). In what scenarios would you choose one approach over another, and what are the operational challenges you've encountered?

Why they ask this:* Tests practical knowledge of modern DevOps tools, understanding of when to apply each technology, and real-world troubleshooting experience relevant to daily cloud engineering work.

You need to optimize cloud costs for a company running 500+ VMs across multiple cloud providers. Walk me through your approach, tools you'd use, and specific cost-saving strategies you'd implement.

Why they ask this:* Evaluates cost optimization mindset (critical for mid-level engineers), familiarity with cloud cost analysis tools, and ability to balance performance with budgetary constraints.

Describe your experience with Infrastructure as Code (Terraform, CloudFormation, or Pulumi). How do you manage state, handle secrets, and ensure reproducibility across environments?

Behavioral Questions

Tell me about a time when you deployed a change to production that caused an outage or performance degradation. What was the situation, what did you do to resolve it, and what did you learn?

Describe a situation where you had to migrate a legacy on-premises application to the cloud. What challenges did you face, how did you plan the migration, and what was the outcome?

Give me an example of when you had to collaborate with a team (developers, DevOps, security) to resolve a technical problem that crossed multiple domains. How did you approach it and what was your role?

Situational Questions

How would you handle a situation where a critical production database is running out of storage, and your team needs a solution within 2 hours, but you've never worked with that specific database technology before?

What would you do if you discovered that your company's cloud infrastructure has a significant security vulnerability (e.g., exposed S3 buckets with sensitive data), but the fix would require downtime during peak business hours?

Q10

Imagine you're tasked with implementing a disaster recovery strategy for a critical system, but leadership has given you a tight budget and limited time. How would you approach this, and what compromises would you propose?
