The "Fundamentals" revolve around a 4-step framework:

Balancing read and write consistency configurations (

Ask about the volume of data and traffic. Establish the number of Daily Active Users (DAU), read/write ratios, and storage requirements over five years. 2. High-Level Design (10-15 Minutes)

To handle millions of concurrent users, traffic must be distributed evenly across a pool of servers. Load balancers act as traffic cops. You should be prepared to discuss:
