Java Full Stack Developer Real-Time Interview | Spring Boot, React, Kafka, Redis, SQL, JWT | 26.7LPA

Java Full Stack Developer Real-Time Interview covering Spring Boot, React, Kafka, Redis, SQL, JWT, Microservices, Hibernate, System Design and Production Scenarios. This mock interview contains real interview questions asked for Java Full Stack Developer roles ranging from 3-8 years experience. Learn how to build a robust Java full stack application. This guide breaks down the architecture connecting React and Spring Boot. This breakdown covers the essential components of a modern Java full stack system. We examine how to integrate React with Spring Boot microservices, ensuring your architecture handles data efficiently using Kafka for messaging and Redis for caching. This content is designed for developers who need to understand how these technologies interact within a production environment.By following this architecture, you will understand the role of an API gateway in managing traffic and how to effectively utilize MySQL for data persistence. We also cover the practical aspects of deploying your services in Kubernetes, moving from local development to scalable infrastructure. You will see how stateless authentication and proper prop management keep your application secure and maintainable.
