Success comes from mastering frameworks that break problems into components (requirements, APIs, data modeling, scalability), practicing with realistic scenarios, and learning to articulate design decisions. Key preparation strategies include using structured learning platforms, practicing mock interviews, understanding fundamentals like caching and consistency models, and internalizing trade-offs rather than memorizing patterns. ## Full article daily.dev links to this article rather than hosting it.
