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 company blog lists AWS S3, EMR, and RDS. For each service, briefly describe its typical role in a modern data platform (storage, compute, metadata/catalog), one common misconfiguration or pitfall that affects data pipelines, and one question you would ask in an interview to confirm how the team uses it.

You read that the company emphasizes "low-latency analytics for near-real-time dashboards". What operational metrics and SLAs would you expect for data pipelines (e.g., end-to-end latency, freshness, failure rate), and how would these influence the design choice between a streaming (Kafka/Flink) approach and a micro-batch (Spark/EMR Airflow) approach?

A case study describes repeated outages caused by schema changes that broke downstream jobs. Propose an automated data validation and contract-testing framework that integrates with CI/CD, handles very large datasets efficiently, minimizes false positives, and catches regressions early. Include sampling strategies, lineage checks, and how to surface failing contracts to producers.

Behavioral: Describe a time you joined a team and had to quickly learn their infrastructure from public docs and internal artifacts. How did you prioritize what to learn first, who did you ask, and what did you do to reduce your onboarding time and help future hires ramp faster?

You notice sparse mention of observability while researching. Draft an initial two-week observability audit checklist you would run to evaluate pipeline health: essential dashboards to check, logs to collect, quick-win alerts to implement, and information to capture for an on-call runbook.
