## Overview & Hiring Pattern
Uber revolutionized transportation and mobility on a global scale.

Engineering interviews test complex distributed systems, geospatial indexing (H3), high-throughput real-time streaming, and algorithmic mastery.

## What Sophia AI Evaluates in This Track
- 🗺️ H3 Hexagonal Spatial Indexing — Hierarchical spatial resolution, driver lookup radius, and geospatial aggregation for surge pricing.
- 🚗 Real-Time Dispatch Engine — Matching algorithms (Bipartite matching/Hungarian algorithm), WebSocket state management, and backpressure handling.
- ⚡ High Availability at Scale — Ringpop distributed gossip protocol, Cassandra timeseries logging, and Apache Kafka event ingestion.
- 🌲 Tough Algorithmic Challenges — Graph shortest path algorithms, dynamic programming, priority queues, and trie structures.

## Frequently Asked Questions
### Q: Why does Uber use Hexagonal Hierarchical Spatial Indexing (H3)?
**A:** Hexagons have identical distances to all 6 adjacent neighbors (unlike squares with corners), making spatial smoothing, radius expansion, and neighborhood partitioning mathematically optimal for real-time dispatch.

### Q: What is Uber's compensation range for SDE-1 and SDE-2 in 2026?
**A:** Uber offers industry-leading pay: SDE-1 ranges from ₹32–45 LPA and SDE-2 ranges from ₹55–85+ LPA including high US-dollar equity grants.
