1
Location update protocol and adaptive sampling
2
Current position versus location history
3
Geospatial indexing and nearby queries
4
Tenant isolation and per-client policy
5
Privacy, retention, and late updates

4. What Strong Candidates Should Demonstrate

✓Separate high-rate location ingestion from current-position and history queries.
✓Support different client products without leaking tenant data.
✓Balance location freshness, battery use, storage cost, and privacy.
