Interview guide
AWS interviews test service-selection judgment over service trivia — scenario prompts ('design a resilient upload pipeline') probing whether you know when to use which service, its limits, and its cost behavior.
Compute choices: EC2 vs Lambda vs ECS/EKS trade-offs
Storage: S3 classes and lifecycle, EBS vs EFS, durability model
Networking: VPC design, subnets, security groups vs NACLs
Databases: RDS vs DynamoDB selection reasoning, read replicas
IAM: roles vs users, least privilege, cross-account access
Resilience and cost: multi-AZ vs multi-region, savings strategies
Prepare one real architecture you can whiteboard end to end — interviewers trust a deeply-explained system you actually ran far more than surface familiarity with twenty services.

Directly — interviewers build questions from your resume's claims, so every skill and achievement listed becomes fair game. A tailored, honest resume steers the interview toward your strongest material; an inflated one hands the interviewer traps you set for yourself.
