PPG UX/UI Designer interview questions & guide 2026

The following questions represent patterns observed in previous hiring cycles. While the specific focus of your interview may shift depending on the hiring team, you should prepare to articulate your design philosophy and demonstrate your technical proficiency.

Portfolio & Experience

These questions assess your ability to communicate your history and the reasoning behind your past design decisions.

• Tell me about yourself.
• Explain some pieces from your portfolio.

Preparation for PPG is about demonstrating both your technical mastery and your professional maturity. You should be prepared to walk through your portfolio not as a static collection of images, but as a narrative of how you solve complex business problems.

Portfolio Depth – Your portfolio is the centerpiece of your interview. Be prepared to explain the "why" behind every design choice, focusing on the specific constraints you faced and the metrics or user feedback that validated your solutions.

Process Clarity – Interviewers want to see how you move from discovery to delivery. Be ready to articulate your workflow, including how you conduct research, iterate on wireframes, and collaborate with developers to ensure a high-quality implementation.

Strategic Alignment – Understand that PPG operates in a highly technical industry. Demonstrate that you can grasp the broader business context, as your designs must contribute to the company's long-term goals and operational success.

The interview process at PPG generally consists of three distinct stages designed to evaluate both your technical fit and your ability to work within a team environment. You can expect a progression from an initial screening to more in-depth behavioral and technical discussions. In some instances, you may be asked to complete a design exercise using provided company assets to assess how you work within established brand guidelines.

The process is intended to be a mutual discovery. While the company assesses your skills, you should use these interactions to gauge the team's culture and the nature of the projects you would be leading. Maintaining clear communication throughout this period is essential.

The timeline above illustrates the standard progression from a phone screen to a final team-based interview. Candidates should use this structure to pace their preparation, ensuring they are ready to discuss their portfolio in detail by the second stage and are prepared for a potential design task in the final phase.

Portfolio & Design Rationale

This area is the most critical component of your evaluation. Interviewers are looking for evidence that you understand the relationship between design choices and project outcomes. Strong candidates demonstrate a clear logic flow, showing how they identified a user problem, explored potential solutions, and arrived at the final design.

Be ready to go over:

• User research methods – How you gather and synthesize data to inform your design.
• Iterative design – Demonstrating how you handle feedback and refine your work.

As a UX/UI Designer at PPG, you are responsible for the end-to-end design lifecycle. You will work closely with product managers to define requirements and with engineering teams to ensure that your designs are implemented accurately. Your day-to-day work involves creating wireframes, high-fidelity prototypes, and design systems that maintain consistency across various digital touchpoints.

Beyond individual design tasks, you will act as a champion for the user. This involves conducting usability testing, analyzing user feedback, and continuously looking for ways to improve existing interfaces. You will be expected to manage your time effectively across multiple projects, ensuring that you meet deadlines while maintaining the high standards expected at a global company.

A strong candidate for this role possesses a blend of high-level creative thinking and technical execution skills. You must be able to demonstrate proficiency in industry-standard design tools and show that you can adapt to the unique requirements of the industrial sector.

• Must-have skills – Proficiency in industry-standard design software (such as Figma or Adobe Creative Suite), a solid understanding of responsive design principles, and experience creating design systems.
• Nice-to-have skills – Familiarity with front-end development constraints (HTML/CSS), experience with accessibility standards (WCAG), and a background in working within large-scale, complex enterprise environments.
• Soft skills – Exceptional communication skills, the ability to manage stakeholder expectations, and a proactive approach to problem-solving.

Q: How long should I expect the interview process to take? A: While timelines can vary, the process typically involves three rounds. You should be prepared for the process to span several weeks, so stay engaged and maintain communication with your recruiter throughout the stages.

Q: What makes a candidate stand out? A: Candidates who stand out are those who can clearly articulate the business impact of their design work. Showing that you understand how your design improves efficiency or user satisfaction—rather than just focusing on visual aesthetics—is highly valued.

Q: Will I be required to do a design test? A: Some interview loops include a design exercise using company-provided assets. If this is requested, focus on following the instructions precisely and demonstrating how you integrate your process into the company’s existing design language.

Q: What is the culture like at PPG? A: PPG is a global company that values precision, professionalism, and collaboration. You will be expected to work effectively in a structured, matrixed environment where cross-departmental coordination is key to success.

• Own your portfolio: Be prepared to discuss every decision in your portfolio. If there was a constraint or a compromise, own it and explain why it was the right decision at the time.
• Prepare for ambiguity: You may be asked to solve problems where you don't have all the information. In these cases, show your thought process by asking clarifying questions before jumping to a solution.
• Focus on the "Why": Never present a design without explaining the reasoning behind it. Your ability to connect design to business value is a core evaluation metric.
• Research the company: Familiarize yourself with the products and industries PPG serves. Understanding the context of the user will elevate your interview performance.

The UX/UI Designer role at PPG offers a unique opportunity to apply design thinking to complex, high-impact industrial challenges. By focusing on your design rationale, demonstrating your ability to collaborate across functions, and clearly articulating your process, you will position yourself as a strong candidate. Preparation is the most effective way to handle the rigor of the interview stages and ensure you feel confident when discussing your professional experience.
