Sudden metric drop, no recent deployments. What's the cause?
This tests your ability to debug data discrepancies beyond code, focusing on the analytics pipeline. First, distinguish data loss from misattribution. Then, check processing delays and hidden data sources. A red flag is not segmenting data first.
This tests your ability to systematically debug data discrepancies when code is ruled out, focusing on the analytics pipeline. A strong answer first distinguishes data loss from misattribution, then checks for processing delays (using data >2 days old), differing attribution models, and hidden offline data sources. The biggest red flag is failing to first segment data by channel, device, or country to find patterns in the drop before hypothesizing causes.
