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.

Given a heavy SQL query that joins a 500 GB fact table and several large dimension tables with window functions and correlated subqueries, outline a step-by-step approach to diagnose and optimize it. Include specific use of EXPLAIN/ANALYZE, checking statistics, rewriting subqueries, creating intermediate or aggregated tables, and when infra changes (partitioning, clustering) make sense.

Design an automated data quality testing framework for raw_events that come from multiple SDKs. Include types of tests (schema, uniqueness, volume, distribution), tooling choices (dbt tests, Great Expectations, custom jobs), CI integration, production monitoring, and an alert/triage workflow for failures.

Design a system that enforces central metric definitions across multiple BI tools and prevents ad-hoc conflicting definitions. Outline the developer workflow for authoring and versioning metrics, CI checks to validate metrics, runtime validation for dashboards, and a migration plan for legacy dashboards.

How would you design an analyst sandbox to enable fast ad-hoc analysis while protecting production systems from expensive queries? Discuss options such as read replicas, sampled datasets, query quotas, sandbox provisioning, and automated cleanup policies.

How would you expose a central semantic layer so both Tableau and Power BI use consistent metrics while allowing analysts to build safe custom calculations? Describe publishing model, certified datasets, access control, and mechanisms to surface provenance and change history.
