Preparation for PubMatic requires a blend of design craft and strategic communication. You are expected to demonstrate how your design decisions contribute to business outcomes while maintaining a high standard of usability.

Role-related knowledge

• You must demonstrate proficiency in standard design tools (Figma, Sketch, Adobe CC) and a solid understanding of design systems. Mastery of data visualization and enterprise UX patterns is highly valued, as these are core to the PubMatic product experience.

Problem-solving ability

• Interviewers look for a structured approach. When presented with a case study, articulate your research, ideation, prototyping, and validation phases clearly. Be prepared to explain the "why" behind every design choice.

Communication and Advocacy

• You will be expected to present your work to cross-functional partners. Demonstrate that you can communicate design rationale to non-designers, such as engineers and product managers, effectively and persuasively.

The interview process at PubMatic is typically extensive, involving multiple rounds of one-on-one sessions with team members and leadership. You should expect a rigorous evaluation that tests both your hard skills through portfolio reviews and your soft skills through behavioral interviews. The process is designed to ensure you can thrive in a highly collaborative, fast-paced environment.

This timeline illustrates the progression from initial screening to potential design presentations and team-wide interviews. Use this to pace your preparation, ensuring you have your best work ready for the deeper technical and portfolio-focused rounds. Be aware that processes can vary by team, so clarify the specific steps with your recruiter early on.

Portfolio Presentation

This is the cornerstone of your interview. It is not just a showcase of your work, but a demonstration of your thought process. Strong candidates treat the presentation as a narrative, highlighting the problem, the constraints, the solution, and the impact.

Be ready to go over:

• The specific user problems you were solving.
• How you navigated trade-offs between design elegance and technical feasibility.
• The metrics or user feedback that validated your design success.

Example questions or scenarios:

• "Walk us through the most challenging project in your portfolio."
• "What was the biggest technical constraint you faced, and how did you design around it?"

Design Strategy and Systems

At PubMatic, consistency is vital. You will be evaluated on your ability to work within or contribute to a design system to ensure a cohesive user experience across the platform.

Be ready to go over:

• Your experience building or maintaining design systems.
• How you ensure accessibility and inclusivity in your designs.
• Your approach to mobile-responsive design for enterprise tools.

Example questions or scenarios:

• "How do you ensure your designs remain consistent with our existing design language?"
• "Describe your approach to creating reusable components for a dashboard."

As a UX/UI Designer, your day-to-day involves more than just wireframing. You will be deeply involved in the product lifecycle, from initial requirement gathering to post-launch evaluation. You will frequently work alongside engineers to ensure your designs are implemented correctly and will meet regularly with product managers to align on feature priorities.

You will likely drive initiatives related to improving platform usability, optimizing data-heavy workflows, and modernizing legacy interfaces. The ability to translate abstract business requirements into concrete user experiences is the primary deliverable of this role. You should view yourself as an advocate for the user who ensures the product remains intuitive despite the underlying technical complexity.

A successful candidate for this role possesses a strong portfolio that demonstrates deep experience with complex enterprise software. You should have a clear grasp of modern design tools and a proven track record of cross-functional collaboration.

• Must-have skills: Proficiency in Figma or Sketch, strong visual design and prototyping skills, and experience with data-heavy UI/UX.
• Nice-to-have skills: Familiarity with front-end development (HTML/CSS), experience in the AdTech industry, and a background in user research methodologies.
• Experience level: Mid-to-senior level designers who can hit the ground running with minimal oversight are typically preferred.

Q: How long should I prepare for the interview process? A: Given the extensive nature of the team-based interviews, allocate at least 2–3 weeks for focused preparation, specifically refining your portfolio presentation and practicing your responses to design case studies.

Q: What differentiates successful candidates? A: The most successful candidates are those who can communicate their design process clearly and demonstrate a genuine interest in the AdTech space. Showing that you understand the business impact of your design choices is a major differentiator.

• Prepare for the presentation: Since you may be asked to present your work, ensure your deck is clean, easy to follow, and tells a compelling story.
