Interaction and User Journey Design Questions

Focuses on the end to end design of how users interact with a product, covering the full user journey and the sequence of steps required to complete tasks. Includes mapping user flows and task flows, identifying decision points and state changes, and handling loading states, error states, failures, recovery paths, and edge cases. Emphasizes navigation and information architecture, transitions and microinteractions, feedback and affordances, and how the interface communicates system status to users. Requires consideration of accessibility and inclusive design, progressive disclosure, and adaptation of interactions across devices and contexts. Candidates should be able to produce and explain deliverables such as annotated flow diagrams, wireframes, prototypes, state tables, and acceptance criteria, justify trade offs and simplifications based on user goals and constraints, and describe how they would test and iterate flows using usability feedback and metrics. Evaluation focuses on holistic thinking across the journey, attention to detail in interaction behavior, and clarity of specifications and documentation for handoff to engineering.

When should a PM use progressive disclosure in an interface? Provide two concrete scenarios where progressive disclosure improves usability, describe the trade-offs between discoverability and simplicity, and list signals you would use to measure effectiveness.

Design an offline-first note sync system that preserves user interactions such as edits, reorderings, and deletions across devices with conflict resolution. Provide interaction specs for sync status, conflict UX patterns, user controls, and acceptance criteria for eventual consistency and data loss prevention.

You ran an experiment that reduced onboarding steps and saw a 10% lift in activation but a 7% increase in early churn. Propose statistical analyses and follow-up experiments to determine whether the trade-off is acceptable and outline potential product changes based on different outcomes.

Create a state table for a complex form submission that includes client-side validation, server validation, slow network, network failure, duplicate submissions, optimistic updates, and rollback. For each state list triggers, user-facing messages, and developer notes for implementation.
