Get ready to dive deep into the object-oriented design of a Hospital Management System, a staple problem for software engineering interviews where correctness meets real-world constraints. This interview experience targets your low-level design muscles: modeling healthcare entities, taming scheduling complexity, capturing medical records and prescriptions safely, and building a reliable billing pipeline.

What You'll Practice:

• Sharpen your ability to gather and refine nuanced, domain-heavy requirements.
• Design a scalable, conflict-aware scheduling architecture.
• Apply key object-oriented principles (encapsulation, inheritance, polymorphism) to clinical and administrative entities.
• Employ design patterns (Factory, Strategy, Observer, Repository, Unit of Work) to keep logic modular and testable.
• Illustrate and explain class relationships and workflows through UML class and sequence diagrams.

By the end of this interview, you’ll be better equipped to handle complex, stateful systems; communicate trade-offs clearly; and deliver precise, privacy-aware, object-oriented designs ready for real-world evolution.
