What This Is
The project question appears in almost every data engineering interview, and it is where most candidates lose ground: not for lack of knowledge, but because they tell it in the wrong order. This guide gives you a repeatable 8-step narration (sources, bronze, silver, gold, consumers, orchestration, with Spark woven in), a complete reference project written out end to end with its architecture and the SQL behind its business logic, a 7-minute spoken model script, the 15 follow-up questions that come next, and a worksheet to build your own. It is built on one rule: tell only what you have done.
What You'll Learn
- Explain your project in a clear 7-minute structure
- Name every data source, layer and business calculation with confidence
- Write the SQL behind the business logic you describe
- Mention Spark optimisations in context instead of as a list
- Answer the challenges question with a problem, diagnosis, fix and result
- Build and rehearse your own project narrative from a worksheet
