## Overview & Hiring Pattern
Zepto has transformed hyper-local commerce in India through its network of tech-enabled dark stores, delivering groceries in under 10 minutes.

Technical rounds rigorously evaluate geospatial indexing algorithms, real-time distributed locking, and high-throughput order processing pipelines.

## What Sophia AI Evaluates in This Track
- ⚡ 10-Minute Dark Store Routing — Dynamic route optimization using Dijkstra/A* algorithms and real-time rider dispatching.
- 📦 Real-Time Inventory Locking — Preventing stock-outs across 500+ dark stores using distributed Redis atomic locks.
- 🗺️ Geospatial Indexing — Uber H3 / Google S2 polygon lookup for sub-second dark store radius mapping.
- 🐹 Go & Python Microservices — Asynchronous workers, Redis Pub/Sub, and Kafka stream processing.
