Prepare to dive into the world of API design with our YouTube API interview. In this exercise, you'll engage in a simulated, structured interview environment designed to reflect real-world challenges and scenarios you might face in the tech industry, particularly at leading tech companies like FAANG+. Over the course of this immersive 40–45 minute experience, you'll confront questions that assess your ability to craft a scalable, efficient, and robust API. The experience is structured to build progressively, challenging your understanding and pushing your design skills to the next level. Get ready to sketch diagrams, think deeply about system interactions, and justify your design choices while adhering to stringent industry standards.

What you'll Practice:

• You'll refine your skills in identifying and articulating functional and non-functional requirements for an API.
• You’ll gain experience in designing essential services and endpoints tailored to meet diverse user needs.
• You'll practice crafting high-level and detailed diagrams that visually represent your API design.
• You’ll tackle complex, thought-provoking scenarios that test your knowledge of API concepts like caching, rate limiting, and data formats.
• You’ll learn to justify architectural choices and respond to counter-questions, deepening your ability to defend and enhance your design decisions.

By the end of this interview, you'll be better equipped to approach API design with confidence and precision. You'll not only understand the intricacies involved in building a robust YouTube API but also be prepared to tackle similar challenges in real-world interview settings.
