Data Engineer Interview Guide: 108 Q&A + Code

A complete, ready-to-use interview preparation guide built for Data Engineer roles at the 3–5 years experience level. Covers the exact stack most commonly tested today — Databricks, Spark, PySpark, DataOps, Python, and SQL.

What's included:

1. 108 questions across 8 sections: General & Foundational, five Technical rounds (Databricks, Spark/PySpark, DataOps, Python, SQL), System Design, Managerial/Behavioral, and HR
2. Every question comes with a full model answer or worked code solution — this is not a bare question list
3. 12 detailed implementation examples with production-grade code (PySpark, SQL, Delta Lake), each explaining why the answer matters and the common gap most candidates miss
4. Difficulty tags ([Easy]/[Medium]/[Hard]) so you can pace your preparation
5. [Red Flag] markers on questions where a vague answer signals a candidate hasn't done real hands-on work — useful for both interview prep and interviewer evaluation
6. A quick-reference cheat sheet summarizing key commands, concepts, and syntax in one scannable table
7. Bonus section: see how the same skill set gets tested differently at mid-size/service companies versus FAANG/MAANG versus AI-infra companies like Anthropic, OpenAI, and Google

Who this is for: Data Engineers preparing for interviews in the 3–5 YOE range, and interviewers/hiring managers who want a structured, ready-made evaluation framework instead of building one from scratch.
