Interview Prompt
Six sources (a CRM, a card-payments feed, a product database, a budget spreadsheet and two weekly file drops) land about 750K records a day on a new Databricks platform, each declared in config rather than code. Design the end-to-end platform that refines them through medallion layers into one semantic layer for the analysts' dashboards.
Summary
Infrastructure as code. Meaning as a service.
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
