Azure Data Engineer Common Interview Questions with Kannan P

Most Data Engineers fail interviews not because they lack coding skills, but because they answer like a textbook.

If an interviewer asks "What is Unity Catalog?" and you answer "It is a governance solution," you are failing the "Senior" check.

This E-book teaches you the "Rich Man’s Strategy"—how to answer questions by focusing on Cost, Architecture, and Business Value. I have compiled the exact answers that turn a standard interview into a job offer.

What’s Inside?

✅ The "Junior vs. Senior" Format: See exactly what not to say, and the winning answer to replace it with.

✅ Modern Tech Stack (2025): Unity Catalog, Liquid Clustering, DABs, and Delta Live Tables.

✅ Performance Tuning Masterclass: How to solve Small Files, Data Skew, and OOM errors (and save cloud costs).

✅ System Design: Medallion Architecture, Bronze/Silver/Gold patterns, and handling Incremental Loads.

Perfect For:

1. Data Engineers (2 to 6 Years Exp) targeting Senior roles.
2. Professionals moving from On-Prem/SSIS to Azure Databricks.
3. Anyone tired of getting rejected in the final round.
