Problem Solving in Ambiguous Situations Questions

Evaluates structured approaches to diagnosing and resolving complex or ill defined problems when data is limited or constraints conflict. Key skills include decomposing complexity, root cause analysis, hypothesis formation and testing, rapid prototyping and experimentation, iterative delivery, prioritizing under constraints, managing stakeholder dynamics, and documenting lessons learned. Interviewers look for examples that show bias to action when appropriate, risk aware iteration, escalation discipline, measurement of outcomes, and the ability to coordinate cross functional work to close gaps in ambiguous contexts. Senior assessments emphasize strategic trade offs, scenario planning, and the ability to orchestrate multi team solutions.

You have two weeks to evaluate whether a marketing campaign improved signup quality. Data includes exposure logs, signups, and downstream engagements; some covariates are noisy. Describe confounders to watch for, which causal methods you'd consider (e.g., propensity scores, IVs), and how you'd present uncertainty and limitations to marketing.
