The interview process at Ecolab is designed to evaluate both your technical proficiency and your ability to navigate the collaborative nature of our teams. While questions may vary based on the specific project focus, you can expect a mix of portfolio-based inquiry and behavioral assessment.

Portfolio and Process

These questions focus on your past work, your ability to articulate your design decisions, and how you approach complex problems from inception to delivery.

• Walk us through your favorite project from your portfolio.
• What was the specific thought process behind the design decisions in this project?

Preparation for Ecolab requires a blend of storytelling and technical clarity. You should be prepared to dive deep into your portfolio, as interviewers will look for evidence of how you think, not just what you have produced.

Design Thinking – This criterion evaluates your ability to articulate the "why" behind your design choices. You should be prepared to walk through your decision-making process, including user research, wireframing, and iteration cycles.

Collaboration and Communication – Ecolab projects are highly cross-functional. You must demonstrate an ability to work effectively with engineers and stakeholders, explaining design intent in a way that aligns with business objectives and technical constraints.

Industry Awareness – Showing that you understand the Ecolab mission is essential. Research the company’s impact on water, hygiene, and sustainability, and be ready to discuss how your design skills can contribute to these specific domains.

The interview process at Ecolab is structured to be thorough yet professional, focusing on assessing your fit for the team and the technical requirements of the role. Candidates can typically expect a progression from an initial recruiter screen to more focused technical discussions and portfolio reviews.

Portfolio Review

This is the cornerstone of your interview. Interviewers will select specific projects from your portfolio to understand your depth of expertise.

Be ready to go over:

• Project Context – Explain the user problem and the business goal.
• Decision Making – Justify why you chose one design path over another.

As a UX/UI Designer at Ecolab, you will be embedded in a team that values iterative development. Your primary responsibility is to create intuitive digital interfaces that simplify complex industrial processes for our end users. You will be expected to own the design process from discovery to final handoff, ensuring that every interaction is purposeful and aligned with user needs.

Collaboration is at the heart of your day-to-day. You will work side-by-side with developers to ensure technical feasibility and with product managers to ensure the solution meets business goals. You may find yourself balancing multiple projects, requiring you to prioritize tasks effectively while maintaining a high level of design quality across all deliverables.

A strong candidate for this role possesses a mix of creative vision and disciplined execution. We look for individuals who can translate abstract requirements into clear, functional designs.

• Must-have skills – Proficiency in industry-standard design tools (e.g., Figma, Adobe Creative Suite), a strong portfolio demonstrating web application design, and experience with user-centered design methodologies.
• Nice-to-have skills – Experience working in industrial or enterprise software sectors, basic understanding of front-end development (HTML/CSS), and experience with design system management.
• Experience level – We typically look for designers who have demonstrated success in previous roles, with a clear history of navigating complex project requirements and delivering results in a team setting.

• Be specific with your metrics: Whenever possible, describe the impact of your work using qualitative or quantitative results.
• Practice your "About Me": Your introduction sets the tone. Keep it concise, professional, and focused on your design evolution.
• Understand the user: Since Ecolab serves diverse industries, showing that you can empathize with non-technical users is a huge advantage.
• Ask thoughtful questions: At the end of your interview, ask about the team’s current design challenges or how they collaborate with engineering.
