Get ready to dive into the design of a food delivery platform, inspired by real-world systems like Uber Eats, DoorDash, or Foodpanda. This interview will test your ability to analyze requirements, propose a scalable architecture, and design robust workflows. You’ll need to think critically about object-oriented principles, concurrency, and extensibility while considering practical edge cases such as delivery delays or unavailable items.

What You'll Practice:

• Refining and prioritizing system requirements.
• Designing a clean and modular object-oriented architecture.
• Applying SOLID principles and relevant design patterns.
• Visualizing class diagrams to explain relationships clearly.
• Anticipating scalability, concurrency, and real-world challenges.

By the end of this interview, you’ll be more confident in tackling system design problems, explaining trade-offs, and creating extensible, real-world-ready architectures.
