Adobe Data Engineer Interview

The Adobe data engineer interview is designed to evaluate both your mastery of fundamental computer science skills and your ability to architect large-scale data systems that support Adobe’s diverse product ecosystem. 

Unlike traditional analytics-focused data engineering roles, Adobe’s data engineering teams work on high-volume, global-scale pipelines powering Creative Cloud, Document Cloud, Experience Platform, and Adobe’s AI/ML systems such as Adobe Sensei. This means you must be equally strong in coding, SQL, distributed systems, data modeling, ETL architecture, and performance optimization.

Adobe expects data engineers to wrangle massive datasets, including images, documents, user telemetry events, personalization logs, and content metadata, and transform them into structured, reliable data products. The interview tests your ability to think clearly, write clean code, optimize transformations, and design fault-tolerant pipelines.

This guide walks you through each stage of the Adobe data engineer interview, including the skills evaluated and how to prepare effectively for the coding, SQL, and system design rounds.
