Covers the end to end practices of gathering, evaluating, synthesizing, and incorporating feedback into iterative design and research cycles. Candidates should demonstrate how they plan and run user research and usability testing, collect feedback from users, teammates, and stakeholders, and use structured synthesis methods such as affinity mapping and thematic analysis to generate actionable insights. Includes practical iteration techniques such as rapid prototyping, playtesting, split testing and controlled experiments, incremental improvements, and versioning of design artifacts. Assesses how candidates prioritize suggested changes using impact and effort considerations, product vision alignment, and technical constraints, and how they define and measure success through quantitative metrics and qualitative signals. Examines interpersonal skills around openness to critique, responding without defensiveness, communicating trade offs and decisions to stakeholders, defending choices with evidence and rationale, documenting learnings, and establishing processes for continuous improvement and knowledge transfer. Also includes learning from past iterations and mistakes and adapting research methodology or recommendations based on new evidence.

Your executive team asks whether to buy a commercial UX analytics platform or build an in-house solution. Outline an evaluation framework comparing total cost of ownership, time-to-value, flexibility for custom metrics, data privacy and ownership, integration complexity, vendor lock-in, and long-term maintenance. List the key questions you'd ask vendors and engineering leads before making a recommendation.

Design a versioning and migration strategy for a major UX overhaul that affects both mobile apps and web clients. Address API compatibility, feature flags, progressive rollout by client versions, data migrations, client version detection, conflict handling, rollback procedures, and how to communicate breaking UX changes to enterprise customers with SLAs.

Explain, in plain terms for non-statisticians, what sample size, statistical significance, and power mean in the context of UX experiments. Provide simple rules of thumb a Solutions Architect might use when advising stakeholders on how long to run an experiment and when to trust results.

Coding (Python): Implement a function `analyze_ab(control_conversions, control_users, variant_conversions, variant_users)` that returns control conversion rate, variant conversion rate, percent uplift, and an approximate two-sided p-value using a z-test. Assume integer inputs, use the normal approximation, handle edge cases like zero users, and aim for clear, commented code with O(1) complexity.
HardSystem Design
53 practiced
Design governance for a single design system used across multiple regions and product lines. Include component ownership and contribution model, semantic versioning policy, enforcement of accessibility and localization standards, release cadence, compatibility guarantees, deprecation workflows, and metrics to measure adoption, technical health, and cross-team compliance.
