## Overview & Hiring Pattern
Java developers face deep questions on JVM architecture, garbage collection algorithms, multithreaded concurrency, and Spring Boot framework patterns. Sophia checks how you design secure, robust enterprise systems.

## What Sophia AI Evaluates in This Track
- In-depth testing on Java JVM memory models, garbage collection, and multithreading
- Tests Core Java Collections framework, Streams API, and Lambdas
- Covers Spring Boot architecture, dependency injection, JPA/Hibernate, and security
- Evaluates microservices patterns: API gateway, circuit breaker, service discovery
