A specific OOPS question was "Explain SOLID principles in Object Oriented Design," for which the candidate elaborated on each principle (Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion) and their role in reducing tight coupling and enhancing code reusability and maintainability.

(discussing issues related to distributed systems, service discovery, redundancy, and load balancing).
