## Overview & Hiring Pattern
Zomato powers restaurant discovery, food ordering, and quick dining across thousands of cities. Its engineering teams build ultra-reliable services using Golang and cloud-native microservices capable of handling massive order surges during festival nights (New Year's Eve, IPL).

The technical interview process evaluates:
1. Low-Level Object Oriented / Modular Design: Creating testable, extensible code for food ordering, table bookings, and delivery allocation.
2. High-Level Architecture & Distributed Systems: Designing sub-millisecond search indexes with Elasticsearch, real-time push notifications, and resilient payment workflows.
3. Concurrency & Performance: Mastering Go channels, memory allocations, garbage collection pauses, and relational database indexing.

Sophia challenges your practical engineering decisions, edge-case handling, and algorithmic communication.

## What Sophia AI Evaluates in This Track
- 🐹 Golang Internals & Concurrency — Channels, Goroutines, GMP scheduler model, sync.Mutex vs sync.RWMutex, context cancellation propagation.
- 🍽️ Real-Time Menu & Restaurant Search — Elasticsearch integration, fuzzy query matching, geo-filtering, and distributed caching.
- ⚡ High-Throughput Notification Engine — WebSockets, push notifications, Redis Pub/Sub, and rate-limiting leaky bucket implementations.
- 📐 Low-Level Design (LLD) — Clean OOP/SOLID implementations for Food Ordering, Rating System, and Table Booking engines.
- 🗄️ Relational & NoSQL Optimizations — PostgreSQL indexing, connection pooling (PgBouncer), MongoDB sharded clusters, and query tuning.
