Design Challenge: Real-Time Product Design
What to Expect
Timed design exercise where you solve a realistic product design problem in real-time, typically in a 60-90 minute session with a designer. You'll be given a brief describing a user problem or product requirement and asked to design a solution using Figma or similar tool. The interviewer will observe your thinking process, how you break down the problem, your design decisions, and how you iterate based on feedback. This round tests your ability to work under mild time pressure, communicate your thinking clearly, handle ambiguity, and respond to real-time feedback. It simulates actual design work where you need to balance perfection with shipping.
Tips & Advice
Start by asking clarifying questions about the brief to demonstrate problem-solving rigor and avoid assumptions. Spend the first 10-15 minutes on user research, persona definition, or problem mapping rather than jumping to design. Create a quick wireframe or structure before focusing on visual design. Think out loud so the interviewer follows your reasoning. Be efficient with tool usage to maximize design time. Create multiple quick iterations or explorations to show you're thinking through options. Be open to the interviewer's suggestions and pivot quickly without defensiveness. Remember that the process matters as much as the final output. Focus on core functionality and clear user flow rather than pixel-perfect details. Leave time to show interactive states (hover, active, error, loading states) which demonstrate maturity. Use common design patterns when appropriate; don't reinvent the wheel.
Focus Topics
