Design a system that allows Rivian service teams to remotely diagnose vehicle issues, push configuration fixes, and schedule service appointments.
Remote diagnostics reduce the need for physical service visits, which is especially important for Rivian since their service center network is still growing. This question appears frequently for candidates joining the service and support engineering teams.
What the Interviewer Expects
- Design a diagnostic data collection pipeline with triggered deep captures
- Build a remote troubleshooting interface for service technicians
- Implement remote configuration pushes to resolve known issues
- Design a DTC (Diagnostic Trouble Code) knowledge base and resolution system
- Handle privacy and consent for diagnostic data collection
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 do you collect detailed diagnostic data only when a specific issue occurs?
- How would you build a system that learns common fixes from historical service data?
- What is the security model for remote vehicle configuration changes?
- How do you handle a situation where a remote fix makes the problem worse?
