• Research methodologies – How you gathered user insights (interviews, surveys, usability testing) and how those insights directly informed your design decisions.
• Information architecture – Your ability to organize complex data, map out user flows, and construct intuitive navigation schemas.
• Interaction design details – The micro-interactions, states, and responsive behaviors that make a digital product feel polished and intuitive.
• Visual design execution – Your use of grid systems, typography, color theory, and adherence to established design systems.

Advanced concepts (less common):

• Designing for multi-modal interfaces (voice, touch, gesture).
• Integrating localized design patterns for global, multilingual user bases.
• Creating generative design layouts based on dynamic data inputs.

Example scenarios:

• Presenting a case study where a design decision was pivoted mid-project due to technical constraints or new user data.
• Explaining how you structured a complex, multi-step checkout flow to minimize user drop-off.

Interactive Whiteboard & Design Exercises

The whiteboard exercise tests your ability to collaborate, think on your feet, and apply design methodology to a prompt in real-time. You are not expected to deliver a polished UI in this round; instead, the focus is on your structured approach to problem-solving.

Be ready to go over:

• Problem definition – Asking clarifying questions to understand the target audience, business goals, and technical constraints of the prompt.
• User persona mapping – Quickly identifying the core user segments and their primary pain points.
• Ideation and sketching – Translating ideas into low-fidelity wireframes on the whiteboard while explaining your thought process out loud.
• Feedback integration – Adapting your sketches in real-time as the interviewer introduces new constraints or critiques.

Example scenarios:

• Designing an in-hospital kiosk system for patients to check in and view their medical appointments.
• Creating a mobile application concept that helps remote field engineers diagnose machinery issues in areas with low internet connectivity.

Design Operations & Strategy Alignment

For mid-to-senior roles, UST Global places a strong emphasis on your understanding of design operations (DesignOps) and how design drives business strategy. They want to know how you scale design processes and collaborate across large organizations.

Be ready to go over:

• Design system contribution – How you build, maintain, and document component libraries to ensure consistency and speed up development.
• Cross-functional handoff – Your process for preparing design specifications, assets, and redlines for engineering teams.
• Strategic operations – How you measure design debt, prioritize design backlogs, and advocate for design quality in agile product teams.

Example scenarios:

• Describing how you successfully advocated for a design system adoption across multiple product lines.
