Performance Troubleshooting and Diagnostics Questions

Diagnosing unexpected changes in campaign or product metrics and driving corrective action. Candidates should demonstrate a systematic troubleshooting process: triage symptoms, gather evidence from analytics and ad platform dashboards, form prioritized hypotheses, test and validate causes, and implement short term fixes and long term remediation. Typical root causes include tracking or attribution failures, landing page errors, creative fatigue, bidding or pacing changes, seasonal or competitive shifts, policy or algorithm updates, and technical regressions. Assess familiarity with investigation tools and signals such as analytics reports, event instrumentation checks, server logs, heatmaps, ad platform diagnostics and experiment logs. Also evaluate communication with engineering, product, and creative partners, and how the candidate tracks and validates recovery with postmortem metrics and monitoring.
