Interview Prompt
We run a multi-tenant platform where multiple internal teams publish events to shared topics. Different teams have added new fields to the event schema independently over time, and the stream processing jobs that consume these topics are now fragile and break on unexpected schema changes. Design a schema-governed streaming pipeline.
