Interview Prompt
Our product runs on a transactional database that the analytics team cannot query directly. We need to replicate it to a separate analytics system where they can run reports. The source data is messy and split across several tables that need to be normalized and combined before it is useful. Design a pipeline to replicate and prepare this data.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
