Interview Prompt
Your platform receives fitness activity events from three external providers, each using a different data format and delivery mechanism. The same workout session can appear from more than one provider simultaneously. Design a pipeline that normalizes incoming events, resolves conflicts when the same session arrives from multiple sources, and routes clean data to downstream consumers.
