In the pen-and-paper round, all candidates were given the same problem statement. I am not entirely certain if this was the exact wording, but the core requirement was to design a system using abstraction and inheritance principles. Specifically, I had to create an abstract class named Hospital, define abstract methods such as getDescription(), and declare the required variables. Then, I needed to create a Person class with a string variable name, extend it into a Patient class, and override the getDescription() method. Additionally, I was asked to implement simple logic such as retrieving the next patient based on priority. The focus of the question was mainly on understanding abstraction, method overriding, class hierarchy, and applying basic low-level design concepts rather than solving a pure data structures problem.
