Quick answer
This backend system interview question asks you to design a global warranty & product service management platform. Aim for a design that meets its requirements at the stated scale, then explain its main components, data flow and trade-offs. Interviewers want to see how you scope the problem, size it and defend each choice.
The problem
Design a Global Warranty & Product Service Management Platform. Major consumer electronics and hardware manufacturers use this system to handle the complete post-purchase lifecycle of their products, ensuring seamless customer support.
When a customer purchases a device, they register its serial number. If the device later malfunctions, the customer files a claim. The platform must instantly validate the warranty status (checking purchase date against dynamic policy rules), assign the claim to the nearest authorized service center equipped for that specific product, and orchestrate the repair workflow.
As technicians update the repair status (e.g., RECEIVED, DIAGNOSING, WAITING_PARTS, REPAIRED), the system must maintain an immutable audit log and trigger real-time notifications to the customer.
What must a global warranty & product service management platform do?
- Product Registration: Allow users to register newly purchased devices to activate their warranty.
- Warranty Validation: Evaluate claim requests against product history and warranty rules to determine eligibility.
