In a real interview, the candidate was asked to design a system for handling high volumes of ride requests, with a focus on latency, throughput, and fault tolerance. The candidate's design involved using a load balancer, multiple application servers, and a database cluster, with a clear explanation of the trade-offs and justifications for each component. The interviewer was impressed with the candidate's ability to think critically and communicate complex ideas clearly.

A common mistake is to focus too much on memorizing specific system design solutions, rather than understanding the underlying principles and trade-offs. A good approach is to practice designing systems from scratch, using a whiteboard or a tool like Diagrams.net, and to focus on communicating complex ideas clearly and concisely. For example, a candidate was asked to design a system for handling real-time updates to a map, and they were able to clearly explain their design and justify their trade-offs.
