Interview Prompt
Design one pipeline to move transactional sales data from multiple regional databases into a centralized analytics layer on GCP, replacing the ad-hoc exports our regional teams run today. The five regions sit in different time zones and each adds a few million sales rows a day, with deals edited for weeks after they are created.
Summary
Sales data, BigQuery, Dataflow. Make it all sing.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
