Interview Prompt
We collect telemetry from millions of connected vehicles - speed, braking events, OBD sensor readings, and ADAS alerts - and need to make this data available to our safety analytics and predictive maintenance teams. Our current setup has no IaC and promoting a pipeline change from dev to prod involves a manual Confluence checklist. Design the pipeline architecture and the operational model for deploying and promoting changes safely.
Summary
Every vehicle is a sensor. Deploy the pipeline to catch it all.
