Step into a challenging, real-world system design interview focused on building Facebook Messenger. You'll be guided through a progressive series of questions that mirror the structure and rigor of top-tier tech interviews. The session covers everything from scoping requirements to architecting a scalable, high-throughput messaging platform—complete with group chats, media sharing, and real-time notifications. Expect to illustrate your ideas, defend your choices, and adapt your designs as you tackle increasingly complex scenarios.

Throughout the experience, you'll engage in a dynamic conversation that tests both your breadth and depth of system design knowledge. You'll be prompted to draw diagrams, justify architectural decisions, and handle curveball questions that probe your ability to think on your feet. The interview is designed to simulate the pressure and expectations of a real FAANG+ interview environment.

Get ready to sharpen your skills in:

• Defining and prioritizing functional and non-functional requirements for messaging systems.
• Designing high-level and detailed architectures for scalable, low-latency platforms.
• Making informed choices about databases, APIs, and real-time communication protocols.
• Illustrating and defending your designs through diagrams and scenario-based questions.

By the end, you'll be better equipped to approach complex system design interviews with confidence, clarity, and a structured problem-solving mindset.
