On UX/UI Designer interview questions & guide 2026

The following questions are representative of the patterns identified in recent interview cycles at On. While individual experiences vary based on the specific team and region, you should prepare for a mix of behavioral, experience-based, and process-oriented inquiries.

Behavioral & Brand Alignment

These questions assess your connection to the On mission and your ability to thrive in a high-performance environment.

• What draws you to the On brand, and how do you see yourself contributing to its evolution?
• Tell me about your background as a designer and the specific motivations behind your career path.

Success at On requires more than just a strong portfolio; it requires an alignment with the company’s intense focus on brand and innovation. You will be evaluated on your ability to articulate your creative process as much as the final output.

Role-Related Knowledge – You must demonstrate mastery over your design toolkit and a clear understanding of UI/UX principles. Interviewers look for evidence that you can translate complex problems into intuitive digital solutions.

Problem-Solving & Innovation – On values designers who can push boundaries. Be prepared to explain how you move from a blank slate to a fully realized concept, emphasizing your ability to iterate and refine ideas based on constraints.

Culture Fit & Communication – Given the brand-heavy nature of the company, showing genuine enthusiasm for the product is critical. Clear, transparent communication is highly valued, as the team looks for partners who can articulate their design decisions effectively to non-design stakeholders.

The interview process at On is characterized by a high degree of focus on design capability and cultural alignment. You should anticipate a process that generally moves from an initial recruiter screen to more in-depth conversations with designers and creative leadership. The pace can be rapid, and the evaluation is often centered on your portfolio, your design process, and your alignment with the company's brand identity.

The timeline visual above illustrates the typical progression from initial screening to potential final-round discussions. Candidates should interpret these stages as a funnel: early rounds focus on broad fit and technical basics, while later stages dive deeper into your specific design methodology and ability to contribute to the unique demands of the On brand.

Design Methodology

This area evaluates how you think. It is not just about the final pixels, but the "why" behind your design choices. Strong candidates demonstrate a structured approach to discovery, ideation, and implementation.

Be ready to go over:

• User-Centricity – How you validate designs through user feedback.
• Iterative Thinking – How you handle critique and refine work under pressure.

As a UX/UI Designer at On, your responsibilities are anchored in the constant evolution of the brand’s digital presence. You will be expected to manage the full lifecycle of design tasks, from initial concept and wireframing to high-fidelity prototyping and final asset delivery.

You will work closely with cross-functional partners to ensure that every pixel aligns with the On aesthetic. This often involves participating in rapid-turnaround projects where you must balance creative exploration with the functional needs of the business. You will likely be involved in managing design assets for various digital platforms, ensuring that the brand voice remains consistent across all customer touchpoints.

A competitive candidate for this role possesses a blend of high-level creative thinking and precise technical execution.

• Must-have skills:

  • Proficiency in industry-standard design tools (e.g., Figma, Adobe Creative Suite).
  • Experience in building and maintaining design systems.
  • A portfolio that demonstrates a strong grasp of modern UI/UX trends and brand-led design.
  • Ability to articulate design decisions clearly to cross-functional stakeholders.

• Nice-to-have skills:

  • Experience in e-commerce or high-growth retail environments.
  • Understanding of front-end development constraints and technical feasibility.
  • Experience with motion design or prototyping for high-fidelity interactive experiences.

Q: How much preparation time should I dedicate to the interview process? A: Given the potential for design tasks or case study presentations, you should budget significant time to review your portfolio and prepare to explain your process in detail. Focus on being able to tell the story of your most successful projects.

Q: What is the most important factor in a successful interview? A: Beyond technical skill, showing a genuine passion for the On brand and its mission is essential. Interviewers want to see that you understand the "why" behind the brand and how your design work contributes to that vision.

Q: What is the typical timeline from the first interview to an offer? A: Timelines can vary significantly. While some processes move quickly, others may involve multiple rounds of review. Maintain clear communication with your recruiter to stay updated on your status.

• Own your process: When asked about a project, don't just show the result. Explain the problem, the constraints, your specific contribution, and the final impact.
• Ask about the team: Use your interview time to ask about how the design team collaborates with engineering and product. This shows you are thinking about the practical implementation of your work.
• Be ready for brand questions: You may be asked about your perception of the On brand. Take time to study their current digital presence and think about how it aligns with their market position.

The UX/UI Designer role at On offers a unique opportunity to influence a brand that is at the forefront of performance and design. By focusing your preparation on articulating your design methodology, demonstrating deep brand alignment, and mastering your technical workflow, you will position yourself as a strong candidate. Remember that your ability to communicate your creative process is just as important as the visual quality of your portfolio.
