Interview Prompt
Analytics queries against the production database are slowing the live application. Move analytics onto its own warehouse fed from the database's change log, while a merchant dashboard shows new orders within fifteen minutes on a path of its own.
Summary
Orders placed. Data warehouse hungry.
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
