Design a restaurant scheduling system that allows customers to make reservations and manage seating efficiently.
This question is typically asked in the onsite interview round to assess a candidate's ability to design scalable and efficient systems. The interviewer is evaluating the candidate's understanding of system architecture, their ability to gather requirements, and how well they can think through the implications of design decisions on performance and user experience.
What the Interviewer Expects
- Clearly define the requirements and constraints of the system.
- Outline a high-level architecture including key components.
- Discuss potential trade-offs in design decisions.
- Identify scaling strategies for handling peak loads.
- Consider user experience and how to handle edge cases.
Key Topics to Cover
How to Approach This
- Start by clarifying functional and non-functional requirements with the interviewer.
- Estimate the scale: QPS, storage, bandwidth. This drives your design decisions.
- Draw a high-level architecture first, then deep dive into 1-2 critical components.
- Discuss trade-offs explicitly (e.g., consistency vs availability, SQL vs NoSQL).
- Address failure scenarios, monitoring, and how the system handles 10x traffic spikes.
Possible Follow-up Questions
- How would you handle double bookings?
- What database schema would you use for this system?
- How would you ensure data consistency in a distributed system?

Requirements
To start, we need to gather the requirements for the restaurant scheduling system. Key functionalities include:
- Customer Reservations: Allow customers to book tables for specific times.

High-Level Design
The high-level architecture will consist of several components:
- Frontend: A web or mobile interface for customers and staff.
- Backend API: A RESTful API to handle requests from the frontend...
