Staff Data Engineer Elite Architecture
AmazonThe User Who Asked to Be Forgotten
Our platform has listeners on mobile, web, and smart speakers - all generating user interaction events. We need to aggregate these into dashboards showing hourly and daily engagement metrics. The challenge is that events arrive late, users can listen across multiple devices in one session, and GDPR requires us to completely delete a user's event history within 30 days of a deletion request. Design the end-to-end pipeline.
Ask the interviewer clarifying questions to understand the requirements and constraints before designing.
