Get ready to immerse yourself in a challenging and engaging API design interview focused on LeetCode, meticulously crafted to simulate the high standards of FAANG+ companies. This experience spans all crucial facets of API Architecture, from functional and non-functional requirements to advanced integration and performance optimization techniques. Over a focused 40-45 minute session, you will delve deep into the architecture and inner workings of LeetCode's hybrid API, making use of both REST and GraphQL. Prepare for a journey where every response will be probed, drawing out your best thinking and problem-solving abilities.

This interview is not just about answering questions but about demonstrating your thought process, decision-making skills, and technical expertise. Expect a mix of straightforward, creative, and follow-up questions, all aimed at assessing your knowledge comprehensively. With the use of text and illustration, you'll get a chance to visualize your solutions and present a well-rounded approach to building a scalable, performant API system.

What You'll Practice:

• Deep-dive into API architectural styles and make informed choices between REST, gRPC, or GraphQL.
• Justify functional and non-functional requirements while splitting a complex system into manageable services.
• Design endpoints and data formats, ensuring optimal performance and security.
• Illustrate your solutions with diagrams using the Drawing Widget to communicate your ideas effectively.
• Explore advanced concepts like API versioning, caching, rate limiting, and more to ensure a robust design.

By the end of this interview, you'll be better equipped to design comprehensive, efficient, and scalable APIs. You'll improve your ability to articulate and defend your choices, ultimately making you more confident and prepared for high-stakes technical interviews.
