Have you previously undergone system design?

Yes, I am familiar with system design. It is the process of designing the architecture of complex systems considering scalability, reliability, performance, and other requirements. In system design, it is important to be able to break down the system into components, choose appropriate technologies, and think through their interactions.

For example, when designing a recommendation system for an ML engineer, one must consider data storage, request processing, model updating, and scaling under load.
