1.1 Hard

Describe a time when you had to redesign an existing interface with significant visual debt while maintaining user familiarity. How did you manage the transition?

What it tests: Ability to modernize interfaces without disrupting user mental models

Sample answer guidance
Should describe the specific visual debt, how they audited the current state, the strategy for incremental versus big-bang redesign, how they preserved navigation patterns and key affordances, and how they tested the new design with existing users. Should mention managing stakeholder expectations about the pace of change.
1.2 Easy

Tell me about a time when you received critical feedback on your visual design work. How did you respond?

What it tests: Receptiveness to feedback and professional maturity

Sample answer guidance
Should describe the specific feedback, their initial reaction, how they evaluated the feedback objectively, and what changes they made. Should demonstrate the ability to separate personal attachment to the work from the goal of creating the best possible design. Should mention how the final result improved.

Culture Fit Questions

Questions that evaluate alignment with company values, work style, and team dynamics.

2 questions in this category.

2.1 Medium

How do you balance creative expression and visual innovation with the consistency requirements of a design system?

What it tests: Understanding of the tension between creativity and system constraints

Sample answer guidance
Should discuss working within system constraints as a creative challenge rather than a limitation, identifying where bespoke design is warranted versus where consistency is more important, proposing system additions when new patterns emerge, and understanding that consistency serves users even when it limits designer expression.
2.2 Easy

What is your approach to creating and organizing icon sets for a product?

What it tests: Attention to detail and systematic approach to visual assets

Sample answer guidance
Should discuss establishing consistent sizing, stroke weight, and style rules, organizing icons by category with clear naming conventions, designing on a pixel grid for crisp rendering, considering both outlined and filled variants, optimizing SVG exports for performance, and documenting when to use icons versus text labels.

Problem Solving Questions

Questions that test analytical thinking, creativity, and structured problem-solving approaches.

2 questions in this category.

3.1 Medium

You notice that the implemented version of your design has subtle but important differences from the Figma mockups. How do you handle this across multiple features?

What it tests: Quality advocacy and systematic approach to design-development fidelity

Sample answer guidance
Should discuss establishing a visual QA process, creating a structured way to document discrepancies, prioritizing fixes by user impact, working with engineers to understand why drift happens, and improving the handoff process to prevent future issues. Should mention design tokens and automated checks where possible.
3.2 Medium

A product team needs a completely new type of component that does not exist in the design system. Walk me through how you would design it and get it adopted.

What it tests: Design system contribution process and component design thinking

Sample answer guidance
Should discuss researching whether existing components can be extended, designing the component with multiple states and variants, documenting usage guidelines and edge cases, reviewing with other designers for broad applicability, collaborating with the front-end team on implementation, and going through the team adoption process.

Situational Questions

Hypothetical scenarios that test judgment, problem-solving approach, and decision-making.

2 questions in this category.

4.1 Medium

An engineer tells you that the animation you designed is causing performance issues on lower-end devices. How do you work through this?

What it tests: Collaboration with engineering and understanding of technical constraints

Sample answer guidance
Should discuss understanding the specific performance bottleneck, exploring simpler alternatives that achieve a similar effect, considering progressive enhancement where animations are reduced for lower-end devices, and being willing to simplify while preserving the core purpose of the animation. Should demonstrate respect for engineering constraints.
4.2 Hard

Your design manager asks you to lead the creation of a dark mode for the product. What is your approach?

What it tests: Systematic thinking about theming and the complexities of dark mode design

Sample answer guidance
Should discuss that dark mode is not simply inverting colors, planning semantic color tokens that map to both themes, adjusting elevation and shadow models, reducing image and icon brightness, handling edge cases like user-generated content, testing for contrast compliance in both modes, and planning a rollout strategy.

Technical Questions

Questions that evaluate domain expertise, technical knowledge, and hands-on skills relevant to the role.

4 questions in this category.

5.1 Hard

Walk me through your process for establishing a visual design language for a new product, including typography, color, spacing, and component styles.

What it tests: Ability to create a cohesive and systematic visual foundation from scratch

Sample answer guidance
Should discuss starting with brand guidelines and product goals, establishing a type scale with clear hierarchy, defining a color palette with semantic meaning and accessibility in mind, creating a spacing system based on a base unit, and building foundational components. Should mention documenting decisions and rationale for future designers.
5.2 Medium

How do you ensure your designs maintain visual quality and consistency across different screen sizes, from mobile to large desktop monitors?

What it tests: Responsive design knowledge and systematic approach to multi-device design

Sample answer guidance
Should discuss designing with a mobile-first or content-first approach, using flexible grid systems, defining clear breakpoints with layout shifts, adapting component sizes and spacing for touch versus pointer interaction, and testing on actual devices. Should mention the design system role in encoding responsive behavior.
5.3 Hard

How do you approach designing data-dense interfaces like dashboards or analytics views while keeping them visually clean and scannable?

What it tests: Ability to handle complex information display with visual clarity

Sample answer guidance
Should discuss establishing clear visual hierarchy through size, weight, and color, using white space strategically, grouping related data, designing progressive disclosure for detail levels, choosing appropriate chart types, and ensuring color use is meaningful and accessible. Should mention testing with real data volumes rather than idealized sample data.
5.4 Easy

How do you choose between using color, iconography, typography, or spatial relationships to create visual hierarchy in an interface?

What it tests: Foundational visual design knowledge and hierarchy principles

Sample answer guidance
Should discuss using size and weight as primary hierarchy tools since they work for all users, using color sparingly for emphasis and status, using spatial grouping and proximity for relationship signaling, and using iconography for recognition and scannability. Should mention accessibility considerations for not relying on color alone.
