What This Is
The Spark round decides most data engineering interviews, and it tests two things: whether you know how Spark works inside, and whether you can reason through a production problem. This pack covers both. The Last-Minute Revision Notes and 91-question Q&A give you the internals, numbers and interview traps. The 43 PySpark and Databricks scenarios teach you to diagnose and fix real production problems out loud, with follow-ups and mistakes to avoid. Revise with the notes, then practise with the scenarios.
