Whiteboard
Basics

Introduction
Landing your dream UX role often hinges on one critical moment: the whiteboard challenge. Whether you're interviewing at Google, Meta, or a promising startup, mastering this skill can make or break your chances. This comprehensive guide reveals what interviewers really look for and how to deliver outstanding performances every time.
What Are Whiteboard Challenges Actually Testing?
Contrary to popular belief, whiteboard challenges aren't just about creating pixel-perfect screens or coming up with "the right answer." They're about simulating the chaos and ambiguity of real-world product design—when deadlines loom, stakeholders are vague, and users are unpredictable.
A whiteboard challenge is less about art and more about thinking in public. It’s an X-ray into how your mind works under pressure.
Here are the 5 key muscles hiring managers are watching for, and how to flex them with intention:
Problem Framing Excellence
Imagine you're asked to "design a better check-in experience at the airport." A junior designer might jump into screens for kiosks or mobile apps. But a thoughtful designer pauses. “Are we talking domestic or international travelers? Solo flyers or families? Which part of check-in—bag drop, security, or boarding?”
Real-life tip: In one interview, a candidate responded to this exact prompt by sketching out the entire system of airport operations, identifying bottlenecks and stakeholder pain points. Instead of designing for the airport, they designed with the constraints of TSA, airline agents, and passenger flow in mind. That level of systems thinking impressed the hiring team more than any wireframe.
🧠 Pro move: Spend 20% of your time just understanding the context. Ask clarifying questions. Define success criteria. Make the interviewer feel like you’ve got this—because you see the forest before the trees.
Structured Thinking
Whiteboard challenges thrive on structure. Think of your board like a storyboard: start with “Problem,” then “Users,” then “Needs,” then “Flows,” then “Solutions.”
Frameworks that shine:
Jobs-to-be-Done: What job is the user hiring this product to do?
User Journey Mapping: Where are the pain points along the user’s path?
How Might We: Reframe problems as opportunities.
Real-life tip: One designer facing a “design a morning routine app” challenge divided the board into time blocks: Wake-up → Get Ready → Commute. Within each, they outlined emotional states and potential frictions. This made their solution feel grounded, intentional, and layered.
📌 Pro tip: Use headers, arrows, and boxes to group ideas visually. The messier your board, the harder it is to follow your logic.
User-Centered Prioritization
Designers often fall in love with clever features. Great designers fall in love with real users. Always ask: who is this for, and what do they struggle with most?
Real-life tip: In a challenge to design a smart home interface for seniors, a candidate began by listing out physical and cognitive constraints seniors might face: small text, memory issues, fear of tech. They then chose to prioritize large buttons, voice commands, and contextual reminders. Every feature they proposed tied directly to a user pain point.
🎯 Pro tip: Draw 1-2 simple personas. Use them like North Stars to justify your decisions. Say things like: “For Mary, who’s 74 and lives alone, the ability to turn off lights from her bed matters more than complex automation routines.”
Clear Communication
The best whiteboarders aren’t just designers—they’re narrators. You're not just drawing, you're storytelling. Talk as you sketch. Share your thought process, your trade-offs, your rationale.
Real-life tip: One candidate, while designing a parking app for city drivers, explained: “I’m starting with pain points because frustration is high in this domain. I’ll focus on discovery and decision-making before jumping into interface.” The clarity of this setup gave the interviewers confidence that each line had purpose.
💬 Pro tip: Practice doing mock challenges out loud. Record yourself. If your reasoning isn’t clear to you, it won’t be clear to your interviewer.
Time Management
You've got 30–45 minutes. That’s not enough to build Rome—but it is enough to sketch the blueprint. Treat time like budget.
Suggested pacing:
5–10 min: Define problem and ask questions
10 min: Identify users and map out journeys
10 min: Brainstorm solution ideas
10 min: Sketch main flow
5 min: Summarize trade-offs and next steps
Real-life tip: A candidate once got halfway through designing a food delivery solution—only to run out of time before showing a checkout flow. Despite great ideation, the team passed. Why? They couldn't evaluate the designer’s prioritization under pressure.
⏳ Pro tip: Keep a mental clock. Don’t aim for perfect. Aim for complete enough to discuss trade-offs.
Common Whiteboard Challenge Topics
Prepare for these frequently asked scenarios:
Design a morning routine app for busy professionals
Tip: Focus on identifying time-sensitive tasks, personalization, and moments of friction in the user’s morning flow. Think through key touchpoints like reminders, integrations, or quick actions.
Improve the airport check-in experience
Tip: Consider both physical and digital experiences. Map the current journey, find bottlenecks (like ID verification or baggage drop), and prioritize accessibility, stress reduction, and clarity.
Create a solution to help seniors adopt smart home technology
Tip: Emphasize simplicity, trust, and guidance. Start by defining pain points with onboarding and learning new tools. Consider voice, visual cues, or even remote family assistance.
Design a better food delivery experience for office workers
Tip: Think about constraints like time windows, group orders, or dietary needs. Break down use cases like lunch coordination, corporate perks, or repeat scheduling.
Reimagine the parking experience in urban areas
Tip: Define context-specific user types (e.g. commuters vs. delivery drivers). Focus on wayfinding, space discovery, payment, and real-time availability—possibly layering in environmental factors.
Conclusion
Whiteboard challenges are learnable skills, not innate talents. With consistent practice and the right approach, you can transform from nervous to confident, impressing interviewers with your structured thinking and user-focused solutions.
