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 three same-priority tasks: A) fix a flaky streaming job that occasionally stalls, B) add a missing 'country' field to the analytics warehouse needed by reporting, and C) investigate a modest but rising cloud cost spike. Describe a prioritization framework you would apply (factors, scoring, and stakeholders), and state which task you'd address first and why.

Design an organizational playbook that empowers data engineers to act with bias-to-action under ambiguity while remaining risk-aware. The playbook should define emergency authorization tiers for hotfixes, required testing and rollback criteria, documentation and post-change review expectations, the escalation matrix, and incentive structures to encourage safe fast moves.

Draft a detailed postmortem template tailored for incidents with measurable revenue impact. Include required sections that enforce clarity: impact quantification (revenue/users), timeline, systemic root cause analysis, remediation steps, action items with owners and ETA, communication history, risk assessment, and metrics to validate resolution. Also describe rules to prioritize action items into sprints.

Design a concise experiment to determine whether a 25% drop in post-midnight events is caused by upstream ingestion failure or a downstream aggregation bug. Specify metrics to collect (raw vs processed counts, consumer lag), minimal instrumentation to add, sampling windows, and clear decision criteria that allow you to conclude which side is responsible.

Describe three practical techniques to detect and investigate schema drift when a field's type or semantics change between batches and downstream aggregates begin to deviate. For each technique, explain how to implement it and the trade-offs (cost, false positives, coverage).
