System design interviews have become a critical component of the technical hiring process at top tech companies, especially for mid-level to senior software engineering roles. Unlike coding interviews that focus on algorithms and data structures, system design interviews evaluate a candidate's ability to architect scalable, efficient, and maintainable software systems. In today’s world, where applications must support millions of users, handle large volumes of data, and provide high availability, companies look for engineers who understand distributed systems, microservices architecture, database sharding, caching, message queues, and more. These interviews help assess whether candidates can balance trade-offs between scalability, reliability, performance, and cost. In this article, we will explore System Design Interview Questions & Practice Test. What Makes System Design Interviews Challenging? A 2023 LinkedIn report

Java System Design- Hospital Management System The integration of technology through a popular Hospital Management System (HMS) can be a good example that offers a digital solution to automate processes such as patient registration, appointment scheduling, billing, inventory management, and staff coordination. This article talks about the comprehensive system design of a modern HMS, leveraging Java, Spring Boot, and a microservices architecture. This combination ensures scalability, flexibility, and resilience, that makes it an ideal choice for addressing the complex and ever-growing demands of healthcare institutions. With a primary focus on system design, we will explore the architecture, individual components, data management strategies, security measures, deployment considerations, performance optimization, future scalability, and practical implementation details, all with essential diagrams.
