The data engineer interview process evaluates expertise in designing, building, and maintaining data pipelines. It typically involves technical assessments on SQL, ETL processes, and cloud platforms, alongside problem-solving and coding challenges. Candidates may also face questions on data modeling, system architecture, and optimizing data workflows for scalability and performance.
