AWS Interview Preparation Guide
Read the full guide on docs.beyondyou.my.idAWS interviews at senior levels go far beyond “what’s an EC2 instance?” They test deep understanding of networking architectures, security models, cost optimization, and multi-account governance. This guide covers the topics that consistently appear in cloud platform engineering and DevOps interviews.
Key Takeaways
- Networking: VPC design, Transit Gateway, PrivateLink, Direct Connect, and hybrid connectivity patterns
- Compute: EC2, Lambda, ECS/EKS, and when to choose each based on workload characteristics
- Security: IAM policies, resource-based vs identity-based policies, SCPs, KMS, and security hub
- Storage: S3 storage classes, EBS types, EFS, and backup strategies
- Architecture: Well-Architected Framework, high availability patterns, disaster recovery (RPO/RTO)
Quick Overview
The most common AWS interview question format is scenario-based: “Design a multi-region, highly available architecture for a payment processing system.” Your answer should demonstrate understanding of: regional vs global services, data residency, failover strategies (active-active vs active-passive), and trade-offs between latency, consistency, and availability.
Practical experience matters — interviewers probe for hands-on knowledge. Be ready to discuss specific services you’ve used, production incidents you’ve resolved, and architecture decisions you’ve made. Theory without practice won’t pass a senior-level interview.
