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.
