Data Engineering Interview Mastery: A Practical Guide to SQL, Python, Spark, Cloud, Streaming, System Design, and Real-World Interview Problems

By Rishu Raj

Data Engineering Interview Mastery is a practical, scenario-driven guide designed to help aspiring and experienced Data Engineers prepare for technical interviews with confidence.

Instead of relying on endless lists of memorized questions and answers, this book teaches readers how to think through problems, explain technical decisions, troubleshoot real-world failures, design scalable data platforms, and handle interviewer follow-up questions.

The book covers the core skills expected in modern Data Engineering interviews, including SQL, Python, data modeling, ETL/ELT, Apache Spark, PySpark, Airflow, CDC, cloud data engineering, Kafka, streaming, data quality, system design, reliability, security, and cost optimization.

Readers also get hands-on SQL, Python, and PySpark challenges, real-world scenarios, system-design exercises, mock interviews, senior-level questions, behavioral interview guidance, cheat sheets, and a 30-day preparation plan.

Whether you're preparing for your first Data Engineering interview or targeting a senior-level role, this book is designed to take you from learning concepts to applying them under interview pressure.
