Technical Topics

Depending on the hiring team’s evaluation style, technical assessments for this role typically cover these core areas:

Topic 1: Cloud Architecture, Networking & IAM Security

Preparation Topic

Core cloud primitives (EC2/VMs, VPCs, subnets, route tables, security groups)
Identity and Access Management (least privilege principles, role delegation)
Storage tiers (S3/Blob, block storage) and database connectivity

Preparation Tip: Be ready to diagram a secure multi-tier cloud environment, showing how public traffic routes through load balancers into private subnets.

Topic 2: Containerization & Docker Best Practices

Preparation Topic

Writing clean, multi-stage Dockerfiles for minimal image size
Container networking, volume mounts, and environment configuration
Container security: running non-root users, vulnerability scanning

Preparation Tip: Explain how multi-stage builds reduce container attack surface and accelerate deployment pipeline speed.

Preparation Topic

Building automated CI/CD workflows (GitHub Actions, GitLab CI, Jenkins)
Declarative infrastructure templates (Terraform, CloudFormation)
State file management, plan validation, and automated rollback strategies

Preparation Tip: Walk through a continuous deployment workflow you configured: what checks run on pull requests vs what triggers production releases.

Topic 4: Observability, Logging & Site Reliability (SRE)

Preparation Topic

Monitoring metrics, distributed tracing, and centralized logging
Formulating Service Level Objectives (SLOs) and Error Budgets
High-availability failover, health checks, and autoscaling triggers
