Kantar UX/UI Designer interview questions & guide 2026

The following questions are synthesized from the experiences of past candidates. They are intended to illustrate the patterns of inquiry you will face, focusing on your design methodology, your speed of execution, and your ability to defend your creative process.

Design Methodology and Problem Solving

• How do you approach a design problem when the requirements are ambiguous?
• Can you walk us through a time you had to pivot your design strategy based on user feedback?
• How do you balance the need for aesthetic appeal with the functional requirements of a data-heavy application?

Preparation at Kantar requires a blend of polished storytelling and technical readiness. You are expected to demonstrate not just that you can "make things look good," but that you can solve business problems through design.

Role-related knowledge – You must demonstrate mastery of standard industry tools and design systems. Be prepared to discuss how you maintain consistency across large-scale products and how you handle complex information architecture.

Problem-solving ability – Interviewers look for a structured approach. Use frameworks like Double Diamond to explain your process, ensuring you show how you move from understanding the user's pain point to testing a viable solution.

Communication and Influence – Since you will work with cross-functional teams, your ability to articulate your design rationale is as important as the design itself. Practice explaining your work in terms of business impact and user value.

The interview process at Kantar is rigorous and designed to test both your creative capacity and your endurance in a professional environment. Typically, you should expect a multi-stage process that begins with a recruiter screen, followed by a technical deep-dive with a lead designer, an assessment phase, and a final presentation to a broader team.

The company values a methodical approach to design. They are looking for designers who can demonstrate a repeatable process, consistent output, and a high level of professional maturity. Because this is a global organization, expect your interviews to be conducted by individuals with varying backgrounds, requiring you to communicate your design decisions clearly and concisely.

The timeline above represents a standard progression, but stay prepared for variations based on regional hiring needs. Use the early stages to ask questions about the team's current design maturity and the specific challenges they are facing, as this will help you tailor your later presentations.

Design Process and Iteration

Evaluation here focuses on your ability to work through complexity. A strong performance shows a clear, logical progression from research to wireframes to high-fidelity prototypes.

Be ready to go over:

• User Research integration – How you translate raw data into design requirements.
• Prototyping speed – Your ability to iterate quickly based on team feedback.
• Handling constraints – How you work within the limitations of existing enterprise systems.

Example scenarios:

• "Explain how you would redesign a legacy data table for a mobile-first experience."
• "Walk us through a project where you had to simplify a complex, multi-step workflow."

Stakeholder Management

You will be evaluated on your ability to navigate the collaborative nature of Kantar. Can you take feedback without becoming defensive? Can you explain technical design choices to non-technical partners?

Be ready to go over:

• Conflict resolution – Examples of navigating design disagreements.
• Design advocacy – How you persuade stakeholders to prioritize user experience.

As a UX/UI Designer, you will own the user experience for specific product features or modules. Your day-to-day will involve translating complex research insights into user flows, wireframes, and high-fidelity designs. You will work closely with product managers to define scope and with developers to ensure the final implementation matches your design specifications.

Expect to spend a significant portion of your time on:

• Creating and maintaining design systems to ensure consistency across the product suite.
• Conducting user testing sessions to validate your design hypotheses.
• Collaborating with data scientists to visualize complex datasets in ways that are accessible and intuitive.
• Participating in design critiques and providing constructive feedback to your peers.

A competitive candidate for this position will demonstrate a high level of proficiency with professional design tools and a deep understanding of UX principles.

• Must-have skills: Mastery of Figma or Adobe XD, experience with Design Systems, and a strong portfolio demonstrating complex problem-solving.
• Nice-to-have skills: Experience with data visualization libraries or tools, basic knowledge of HTML/CSS, and experience working in an Agile environment.
• Experience level: Most successful candidates have at least 3–5 years of professional experience, ideally within a product-focused or enterprise software environment.

Q: How difficult are the technical assignments? A: They are generally considered quite complex and time-intensive. Treat them as a real-world project, but ensure you manage your time effectively and ask for clarification on the requirements before starting.

Q: What is the company culture like for designers? A: Kantar is a data-heavy organization. You will find that the culture values evidence, logic, and professional communication. Designers who can "speak the language" of data and business tend to thrive.

Q: How long does the process take? A: The process can take anywhere from 4 to 8 weeks depending on team availability. Be prepared for potential delays and maintain professional communication with your recruiter throughout.

• Structure your portfolio presentations: Use a standard case study format: Problem, Process, Solution, and Outcome. Focus heavily on the "why" behind your decisions.
• Be ready for the "Why Kantar?" question: Show that you understand the company’s role in the market—specifically, how they use data to drive global industry insights.
• Ask about the design team: Inquire about the current design maturity of the team. It shows you are thinking about how you can contribute to their growth.

A career as a UX/UI Designer at Kantar offers the unique opportunity to shape the tools that define how the world understands data. By focusing on your ability to solve complex problems through a structured, user-centered process, you position yourself as a vital asset to their product teams.
