What a Data Modeling interview probes
Data Modeling interviews reward depth over recall: Star schemas, normalization, slowly changing dimensions, and grain decisions. Interviewers rarely stop at a definition. They push on why, ask you to reason through a tricky case, and watch how you structure the answer under a little pressure.
