Marketing Technology Integration and Architecture Questions

Technical and architectural knowledge for integrating marketing technology systems and designing reliable data flows between platforms. Candidates should be able to explain common integration approaches including native connectors, middleware and integration platforms, custom application programming interface integrations, webhooks, extract transform load and extract load transform pipelines, and orchestration versus choreography. They should understand synchronization models such as event driven streaming and batch transfer, real time processing versus batch processing trade offs, and rate limiting and throughput considerations. Core data topics include data mapping and schema alignment, canonical data models, identity resolution and deduplication, single source of truth strategies, and methods for resolving data inconsistencies. Operational and reliability concerns include error handling and recovery strategies, retries and idempotency, latency and throughput trade offs, monitoring and observability, logging and tracing, testing and validation including contract testing and replay testing, and planning for future tool changes through versioning and abstraction. Security and authentication, data privacy and consent management, encryption, and data governance should be addressed as integral parts of any integration design.
