Design & User Experience Topics
User experience design, frontend architecture, and design systems. Includes UX principles, accessibility, and design documentation.
Design Iteration and Feedback
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.
Technical Depth & Areas of Specialization
Every strong candidate has one or more areas of technical depth that go beyond generalist knowledge. Discuss the area(s) where you have the most depth: how you identify it (a subsystem, technology, domain, or class of problem you gravitate toward), a concrete project or accomplishment that demonstrates that depth, how you actively keep that expertise current (reading, communities, side projects, postmortems), and how that depth changes the way you make trade-offs or collaborate with generalists on your team. Areas of specialization are highly individual and role-dependent (examples span distributed systems reliability, accessibility and design systems, security architecture, data pipelines, performance optimization, mobile platforms) - the interviewer should probe the candidate's own stated specialization rather than assume a fixed domain.
Problem Solving When Design Meets Technical Reality
Share examples of times when your design vision met technical limitations or constraints. How did you handle it? Did you compromise, find creative solutions, or work with engineers to implement something unexpected? Discuss your mindset: are you flexible when constraints exist, or do you fight for your design? Demonstrate pragmatism and collaborative problem-solving.
Usability Principles and Heuristics
Covers core usability principles and established heuristics used to evaluate and design user interfaces. Candidates should understand Nielsen style heuristics such as visibility of system status, match between system and the real world, user control and freedom, consistency and standards, error prevention and recovery, recognition rather than recall, flexibility and efficiency of use, aesthetic and minimalist design, help and documentation, and user freedom. Beyond listing heuristics, be prepared to explain how principles like feedback, affordance, discoverability, error prevention, progressive disclosure, accessibility, and reduction of cognitive load influence interaction design decisions. Expect to discuss methods for applying heuristics in practice, for example conducting heuristic evaluations, creating checklists, running usability tests, analyzing metrics such as task success rate, time on task, error rate, and System Usability Scale scores, and iterating designs based on findings. Interviewers may ask for concrete examples of trade offs you made, defects you detected with heuristics, how you prioritized fixes, and how you communicated usability issues to engineers and stakeholders.
Feedback & System Status Visibility
Ensure users always know what's happening: loading states, progress indicators, success confirmations, status updates. Design clear feedback for user actions. Use visual hierarchy, color, animation, and messaging to communicate system status. Reduce user uncertainty.
Game User Interface Systems
Comprehensive knowledge of user interface architecture and interaction systems specific to games. Covers user interface framework design and patterns, layout systems and anchoring, canvas and render ordering, and responsive layout for multiple screen sizes and platforms such as mobile, console, personal computer, and web. Includes event handling and input management for user interface elements across input sources like mouse, touch, keyboard, and gamepad; navigation and state management between screens and menus; implementation of menus and heads up display components; and how user interface communicates with and remains separated from gameplay logic. Also addresses performance considerations such as batching and pooling, animation and transition systems for interface elements, localization and accessibility for interfaces, testing and debugging user interface flows, and familiarity with common engine frameworks and tooling such as the Canvas system in Unity and the Unreal Motion Graphics system in Unreal Engine.
Interactive States & Micro Interactions
Include interactive states in your designs: hover states, active states, error states, loading states, empty states, disabled states. Explain the purpose of micro-interactions in your design. Show that you think about the complete user experience, including edge cases. Use Figma prototyping or describe interactions clearly.
Responsive and Multi Platform Design
Covers designing user interfaces that adapt across screen sizes and platforms, including mobile, tablet, desktop, web, and native applications. Topics include responsive thinking, mobile first strategy, adaptive versus fluid layouts, responsive grids and breakpoints, component adaptation and scalability, platform specific patterns and conventions (for example iOS versus Android versus web), interaction differences for touch versus pointer devices, performance and accessibility considerations across viewports, and techniques for testing and validating layouts on varied devices. Interview assessment focuses on how candidates make layout and component tradeoffs, choose breakpoints and scaling rules, maintain visual and interaction consistency while respecting platform constraints, and communicate responsive solutions to engineers and stakeholders.
User Interface and Implementation Considerations
Practical considerations for implementing user interfaces and how interaction design ties to runtime behavior, particularly in interactive domains such as games or complex applications. Topics include UI architecture patterns, canvas and scene systems, responsive layout and input handling, handling gameplay or real time events, performance and frame rate implications of UI rendering, preventing input blocking and race conditions, platform specific input differences, and testing strategies to avoid UI bugs. Candidates should demonstrate understanding of how design decisions affect engineering constraints and runtime reliability.
