Geospatial and Real Time Processing Questions

Covers design and operation of systems that handle spatial data and low latency event streams. Candidates should explain spatial indexing and query techniques, map matching and coordinate reference considerations, spatial accuracy and privacy trade offs, and storage approaches for geospatial data. For real time processing describe ingestion, messaging patterns, stream processing concepts such as windowing and stateful processing, ordering and delivery semantics, partitioning and scaling strategies, backpressure and fault handling, and trade offs between real time and batch analytics for customer facing metrics.
