Get ready to immerse yourself in an authentic interview experience simulating a high-stakes API design session at top tech companies! This 40–45 minute challenge centers on designing the API for Slack, the widely used real-time collaboration and messaging platform. You’ll navigate real-world challenges such as defining service endpoints, supporting real-time message delivery, managing channels and workspaces, and ensuring scalability while maintaining low latency and security. Guided by Edward, an adaptive and knowledgeable interviewer, you’ll progress through increasingly complex stages that require both textual explanations and visual diagrams to demonstrate your problem-solving skills.

What You'll Practice: -Dive into comprehensive API design, addressing both functional and non-functional requirements. -Master the design of service endpoints for messaging, channel management, file sharing, and integrations. -Enhance your understanding of key concepts like event-driven architecture, rate limiting, and API versioning. -Explore architectural choices such as REST, WebSockets, and gRPC, and justify their use cases. -Develop the ability to illustrate and communicate complex architecture diagrams and data flows effectively.

Outcome: By the end of this session, you’ll be prepared to tackle intricate API design interviews, clearly articulate trade-offs, and demonstrate the ability to design scalable, real-time, and secure collaboration platforms.
