Design the backend for a restaurant workforce scheduling system.
A company operates many restaurants. Each restaurant has employees and managers. Every week, a manager prepares the schedule for the following week and must publish the final version by Friday.
Design a system that supports:
- Modeling companies, restaurants, employees, and managers.
- Creating and editing a weekly schedule for a restaurant.
- Assigning employees to shifts.
- Publishing the schedule so employees can view the official version.
- Handling many restaurants and growing traffic over time.
Focus especially on the data model, but also explain the high-level architecture, key APIs, scalability considerations, and how you would keep schedule data consistent.
