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.

The product team asks for a 'better recommendation model' but want quick wins. Propose five low-effort experiments or heuristics a data scientist could test in the next two weeks to demonstrate value quickly. For each, state expected upside, downside, and the data required.

As a senior data scientist, propose an organizational change (rituals, roles, KPIs, escalation paths) to improve coordination between ML engineers, data engineers, and product managers for ambiguous projects. Explain why each change helps and how you'd pilot and measure success over 3-6 months.

You discover that the training data contains biased sampling that harms a minority user group. Create a prioritized action plan to audit the model, quantify disparate impact, remediate bias (data collection, weighting, modeling), communicate findings to stakeholders, and implement preventive controls to avoid recurrence.

Explain the difference between exploratory and confirmatory analysis in the context of experiments. When you have limited data and high business risk, which would you prioritize and why? Provide an example relevant to a feature-launch decision.

Write a SQL query (standard SQL) to return user_id and avg_events_per_day for users who, over the past 7 days, had an average events/day > 3 * median daily events across all users. Table: events(event_id PK, user_id, event_type, occurred_at timestamp). Explain any assumptions about timezones and aggregation windows.
