Staff Data Engineer Enterprise Architecture
Three Regions, One Report
A fintech company processes billions of payment transactions per day across three regions: US, EU, and APAC. Each region writes raw payment logs to its own object storage bucket. The data team needs a batch pipeline that runs daily, ingests the previous day's logs from all regions, deduplicates events, aggregates to a merchant-level summary table, and makes results available for global reporting by 6 AM UTC. Design this pipeline.
Ask the interviewer clarifying questions to understand the requirements and constraints before designing.
