Why don't analytics and backend user counts match?
This tests your systematic debugging and understanding that 'user' has different definitions. A good answer first defines 'user' in each system, then investigates tracking implementation, timing differences, and filtering.
This tests your ability to debug data pipelines by understanding that 'user' is defined differently across systems. A great answer first clarifies the definition of 'user' in both the analytics tool and backend, then outlines an investigation into tracking implementation, ETL job failures, timezone alignment, and filtering (bots, ad-blockers). A red flag is immediately blaming one tool without first establishing a shared definition of the metric.
