Sports Product Sense & UX Strategy

Designing for fantasy sports requires an understanding of gamification, real-time data, and high-urgency user flows. Interviewers want to see if you can design experiences that keep users hooked, informed, and confident during fast-paced interactions.

Be ready to go over:

• Gamification and Engagement – How to make routine actions, like entering a contest or drafting a player, feel exciting and rewarding.
• Data Density Management – Techniques for presenting complex player stats, historical data, and live scoring clearly on small mobile screens.
• User Trust and Clarity – Designing transparent flows for financial transactions, entry confirmations, and rules.
• Advanced concepts (less common) – Designing for multi-state interfaces (e.g., pre-draft, live-draft, and post-draft screens) and handling offline/low-connectivity states during live events.

Example questions or scenarios:

• "How would you redesign our current drafting lobby to make it easier for a first-time user to find and enter a contest?"
• "Walk us through how you would display a player's injury status and game-day projections without cluttering the main drafting interface."

High-Fidelity UI & Mobile-First Execution

The Underdog Fantasy mobile app is the primary touchpoint for most users. Your ability to design polished, responsive, and visually compelling mobile interfaces is critical.
