Interview Prompt
Incremental CDC deltas arrive, but the warehouse table is append-only, so an updated order shows up as two rows and downstream counts are wrong. Design the load so an update replaces the prior version instead of duplicating it.
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
