Understanding the Company's Infrastructure Context Questions
Research the company's public infrastructure information (engineering blog, tech talks, published case studies, job description). Understand what systems they operate at scale, what problems they likely face, and what your role would contribute to.

A mid-size company is expanding internationally and must choose between self-managed VMs (IaaS) and managed platform services (PaaS like managed DBs and managed k8s). As a software engineer contributing to infra decisions, compare the two approaches in terms of developer velocity, reliability, cost, operational burden, and vendor lock-in. Provide a pragmatic recommendation and a migration plan that minimizes disruption.

A blog notes the company uses Azure for compute and GCP for machine learning workloads. As an engineer, evaluate plausible technical and business reasons for this split (for example: specialized ML services, pricing, existing contracts). Identify operational complications this brings (CI/CD, IAM, networking, observability) and propose mitigations to provide a smooth developer experience.

Propose an approach to reconstruct the company's service dependency graph when you join with limited internal access. Use publicly available telemetry, passive tracing samples, DNS/service registry observations, and lightweight runtime probes. Describe heuristics for inferring caller-callee relationships, handling fan-in/fan-out, and validating the generated graph with minimal disruption.

The company reports a monthly cloud bill of ~$1.2M with highly spiky traffic and large egress charges for media. As an infra engineer, propose a prioritized roadmap of quick wins and long-term projects to reduce spend while maintaining availability. For each item include estimated effort, expected savings range, and risk level (low/medium/high).

The job listing emphasizes 'multi-cloud experience' and the engineering blog references use of both GCP and AWS. As an incoming software engineer, explain the likely technical and business reasons for a multi-cloud approach, identify three cross-cloud operational challenges they probably face, and prepare five targeted interview questions to assess the company's maturity across multi-cloud operations (CI/CD, IAM, networking, monitoring).
