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 must implement a small utility in Python to merge overlapping time intervals, but the spec is ambiguous about whether endpoints are inclusive and whether input intervals may be unsorted or overlap by microseconds. State any assumptions, then implement a robust function merge_intervals(intervals: List[Tuple[int,int]]) -> List[Tuple[int,int)]. Include complexity constraints and tests.

Design a two-week rapid prototyping process for validating a cross-team feature that touches frontend, backend, and analytics. Outline milestones, minimal deliverables to learn, roles and responsibilities, required instrumentation, and how you would decide to continue, pivot, or stop after two weeks.

Design a lightweight decision framework (one-page) to help product and engineering prioritize work under ambiguous ROI and conflicting constraints (budget, time, regulatory). Describe the axes, scoring approach, and how you ensure transparency and consistency across teams.

Design a lightweight prototype experiment (2-week scope) to validate whether a proposed UI change will increase task-completion rate. Specify success metrics, minimal instrumentation to collect, rollout plan (canary vs. full), and how you would stop or iterate based on early signals.

You see short spikes of 95th-percentile latency in one region of your service but logs are sparse and tracing sampling is low. System handles ~100k requests/min. Propose an immediate investigative plan (first 24 hours): what telemetry to add or change, quick mitigations, and how you'd avoid making changes that disrupt production traffic.
