Interview questions in Design & UX, page 3
How do you fulfill a GDPR erasure request across data stores?
This tests cross-system deletion under GDPR's 30-day SLA. A strong answer maps PII lineage across S3, databases, and analytics; uses soft deletes for backups; and handles dashboards via reprocessing.
Assess WCAG AA contrast for light grey text on off-white
Tests your fluency in WCAG relative luminance and design collaboration. A strong answer extracts sRGB values, computes contrast ratio, checks 4.5:1 or 3:1 by text size, and suggests a darker tint preserving hue.
Implement a typographic scale using design tokens and accessible properties
Token-driven typography and accessibility. Start with base size (14-16px) and ratio token, compute sizes, then bundle font-size with line-height, letter-spacing, weight, and family in composite tokens. Red flag: ignoring line-height, spacing, or composites.
Outline an NLP pipeline to categorize reviews and identify pain points
Tests text mining pipeline design. Answers cover deduplication and normalization, then clustering or topic modeling for categories, plus sentiment analysis to rank pain points. Red flag: skipping validation or jumping to LLMs without cleaning.
Design a next-best-article recommender
Content-based on article embeddings, collaborative on behavior, a hybrid blend, popularity or onboarding fallbacks for new users.
Design a centralized consent platform: core components and database schema
Separate CMF from CMP; build an append-only ledger with versioned wording, per-activity granularity, and real-time revocation.
How would you optimize and implement a full-bleed responsive hero image?
Use srcset with AVIF/WebP, CSS object-fit cover, and width/height to prevent CLS.
Design token pipeline serving Web, iOS, and Android
This tests cross-platform design system architecture and governance. A strong answer uses W3C JSON tokens in option, decision, component layers, with Style Dictionary generating Web, iOS, and Android outputs. Red flag: using Figma or CSS as source of truth.
Building a scalable icon system in Figma
Standardize a grid, size, and stroke; make each icon a component with consistent naming, use currentColor-friendly single-color paths, and export optimized SVGs.
Choosing a spacing scale for a design system
A numeric base-grid gives predictable math, semantic t-shirt names give readable intent, often combine them.
Apply differential privacy to user behavior queries and explain epsilon trade-offs
Mastery of formal privacy guarantees and noise-based query systems. Inject Laplace or Gaussian noise scaled to query sensitivity; track cumulative epsilon across queries; lower epsilon tightens privacy but increases variance and error bars.
Propose a multi-armed bandit system to optimize headlines faster
This tests online learning and the explore-exploit tradeoff. Answers contrast fixed A/B with adaptive allocation, sketch a Bayesian bandit service with a min exploration rate, and note delay.
Propose an automated de-identification pipeline for video interview recordings
Propose CV redaction, ASR/NLP for names, human QA, and consent tracking; note model bias and re-ID risk.
How would you structure a multi-theme color system in Figma and CSS?
Primitives and Semantic collections with theme modes; pipeline to CSS variables; components use semantic tokens only.
Describe a robust architecture for implementing theming using design tokens
Three tiers, CSS custom properties for live switching, and layered overrides.
How would you design a centralized copy service for consistent UI text?
This tests separation of UI and content. A strong answer uses a key-value map with semantic IDs, a lookup hook, and context injection so components call copy.button.save. Red flag: raw strings in JSX or a database for static English-only copy.
What trade-offs matter between moderated usability tests and surveys?
Whether you align research method to product risk and insight type. Great answers contrast surveys for scalable opinions against moderated tests for behavioral observation, weighing fidelity and speed.
How do you build a responsive Figma component across breakpoints?
Tests Figma auto layout and constraint logic for responsive components. Strong answers mention nested frames, hug/fill modes, breakpoint variants or variables, and resizing previews. Red flag: copying static frames instead of using constraints.
How do you handle a one-off token exception for a campaign?
Tests balancing speed and systemic consistency. Strong answers outline a governance fast-track with sunset clauses, document the exception, and isolate it via campaign overrides instead of mutating core tokens. Red flag: permanently hardcoding the one-off.
How would you architect a white-label content system for multiple brand voices?
Tests content-presentation separation for multi-tenant apps. Strong answers use a headless CMS with tenant keys, a domain resolver for brand voice, and shared components with injected strings. Red flag: duplicate codebases or hard-coded copy per client.
