Airbnb-Specific Data Patterns Questions
Domain-specific data modeling and analytics patterns used in Airbnb-scale product analytics. Covers data schema design, event and transaction patterns, feature engineering templates for predictive models, cohort and lifecycle analytics, geospatial and temporal data patterns, price and demand forecasting signals, AB testing data patterns, and data quality, governance, and lineage considerations relevant to Airbnb data.

Describe the SLOs you would set for an analytics pipeline powering dashboards at Airbnb (freshness, latency, availability, accuracy). For each SLO, define how you would measure it, what alert thresholds you'd set, and a basic remediation playbook for common failure modes (e.g., ingestion lag, stale aggregates, missing partitions).

Design an analytics-ready event schema for a "booking_confirmed" event used by Airbnb product analytics. Include required fields, data types, cardinality notes, and an example JSON payload. Fields to consider: booking_id, guest_id, host_id, listing_id, price_breakdown (base, cleaning_fee, service_fee, taxes), currency, checkin_date, checkout_date, booking_created_at, platform (web/android/ios), device_id, experiment_metadata. Explain why each field is important for downstream analytics and how you'd version the schema.

Design a feature store architecture for Airbnb demand forecasting that must serve both low-latency online features and batch training features. Describe the schema for features, feature granularity (listing-day, listing-hour), freshness SLAs, batch vs streaming feature computes, TTL/retention, and how to guarantee consistency between offline training features and online serving features.

For a 'similar listings' recommendation feature, outline a data engineering pipeline that builds feature vectors combining geospatial, price, amenity, and textual embedding features. Include offline batch computation, feature storage format, ANN index strategy (e.g., Faiss/Annoy), update cadence, and considerations for online serving and freshness.

Propose a schema and ETL design to build a guest-host interaction graph for fraud detection that supports k-hop neighbor queries. Include choices between graph databases (e.g., Neo4j) vs adjacency tables in data warehouse, how to integrate streaming updates from bookings/messages, and approaches for scalable graph traversal or offline graph feature extraction for ML.
