Analytics Architecture and Reporting Questions

Designing and operating end to end analytics and reporting platforms that translate business requirements into reliable and actionable insights. This includes defining metrics and key performance indicators for different audiences, instrumentation and event design for accurate measurement, data ingestion and transformation pipelines, and data warehouse and storage architecture choices. Candidates should be able to discuss data modeling for analytics including semantic layers and data marts, approaches to ensure metric consistency across tools such as a single source of truth or metric registry, and trade offs between query performance and freshness including batch versus streaming approaches. The topic also covers dashboard architecture and visualization best practices, precomputation and aggregation strategies for performance, self service analytics enablement and adoption, support for ad hoc analysis and real time reporting, plus access controls, data governance, monitoring, data quality controls, and operational practices for scaling, maintainability, and incident detection and resolution. Interviewers will probe end to end implementations, how monitoring and quality controls were applied, and how stakeholder needs were balanced with platform constraints.

Design a global pipeline to compute a small set of metrics with sub-5-second freshness. Discuss event transport, edge/region aggregation, stateful stream processing, processing guarantees (at-least-once vs exactly-once), idempotent writes, and techniques to achieve eventual correctness for global aggregates.

Finance requires nightly accurate revenue for books while product wants near real-time revenue dashboards. Propose a data flow that serves provisional near-real-time revenue and an authoritative nightly close, including flags to distinguish provisional vs final, reconciliation checks, and stakeholder-facing UI considerations.
