Ambiguity Navigation and Decision Making Questions
Covers approaches to solving ill defined problems: structuring ambiguity, articulating assumptions, generating options, running rapid experiments or analysis, and choosing defensible solutions. Includes communicating reasoning, surfacing unknowns, when to postpone decisions, and building plans that tolerate uncertainty.

Propose three lightweight prototype patterns to validate device-capability features (camera focus modes, location accuracy) across device fragmentation. For each pattern, state what unknown it validates and approximate time to get results.

As a staff mobile engineer, propose a team-level process to institutionalize ambiguity navigation: how to capture assumptions, run quick experiments, decide, and store decisions for future audits. Include tooling, lightweight templates, and how you'd measure process effectiveness.

Design a complete A/B experiment for a new onboarding flow intended to reduce 7-day churn. Specify the hypothesis, primary and secondary metrics, sample size estimation assumptions, randomization strategy, guarding against interference, and a rollout plan that tolerates ambiguous early signals.

Write compact pseudocode (language-agnostic) that implements a persistent A/B assignment using remote config and local storage. The pseudocode should show: fetching remote config, assigning variant deterministically, persisting assignment across app restarts, and logging exposures to analytics.
