Successfully interviewing for a UX/UI Designer role at Johnson Controls requires a balance of deep craft expertise and an understanding of the industrial domain. You must show that you are not just an artist, but a system thinker who can design for safety, utility, and scale.

Role-Related Knowledge – You must demonstrate a strong grasp of design principles, particularly around data visualization, information architecture, and complex B2B workflows. Be ready to discuss how you design for accessibility, responsive layouts, and technical constraints.

Problem-Solving & Systems Thinking – Interviewers want to see how you dissect complex, ambiguous problems. You should be able to explain how you map out end-to-end journeys that involve both digital systems and physical environments.

Collaboration & Influence – As a designer in a large engineering-driven organization, you will need to collaborate with product managers, software developers, and hardware engineers. You must prove that you can defend your design choices with data and user insights while remaining open to technical feedback.

The interview process at Johnson Controls is structured to evaluate both your technical design capabilities and your ability to collaborate in a global enterprise. While the exact steps can vary slightly depending on the location and the specific team, the overall flow remains consistent and thorough.

The journey typically begins with an initial outreach or recruiter screen to establish basic alignment. From there, you will move into a combination of behavioral assessments and deep-dive technical discussions with the hiring manager. The final stage is a comprehensive panel interview where you will present your work to other designers and cross-functional team members.

The timeline above outlines the typical stages you will navigate during the UX/UI Designer hiring process. Candidates should expect the entire journey to take anywhere from three to six weeks, depending on the availability of the panel and the specific office location. Use this timeline to pace your preparation, ensuring your portfolio is fully polished before reaching the final round.

To pass the rigorous interview loops at Johnson Controls, you must perform exceptionally well across several core evaluation areas. Understanding these areas will help you tailor your portfolio presentation and behavioral stories.

Portfolio Presentation & System Design

This is the most critical technical round of the interview process. You will present your work to a panel of 5 to 6 designers and product leads, walking them through your design journey and explaining a key project in detail.

Be ready to go over:

• Information Architecture – How you organize complex hierarchies of data and navigation.

As a UX/UI Designer at Johnson Controls, your daily work will directly influence the usability of enterprise-grade industrial software. You will be responsible for translating complex building automation requirements into seamless digital experiences.

Your primary responsibilities will include:

• Designing intuitive user flows, wireframes, high-fidelity mockups, and interactive prototypes for web, mobile, and specialized hardware interfaces.
• Collaborating closely with product managers to define user requirements, map out customer journeys, and translate business goals into design strategies.
• Partnering with engineering teams to understand technical constraints, explain design intent, and ensure high-fidelity implementation of your UI designs.
• Conducting user research, usability testing, and heuristic evaluations to continuously validate and iterate on your design solutions.
• Contributing to and expanding the global Johnson Controls digital design system to ensure design consistency across all product lines.

You will typically work in an agile environment, collaborating daily with product owners, front-end developers, QA engineers, and industrial designers to bring complex smart-building features to life.

To be competitive for this role, you must demonstrate a strong background in UX/UI design, specifically within complex B2B, SaaS, or industrial domains.

• Must-have skills:

  • A highly polished design portfolio demonstrating end-to-end UX/UI design process, complex workflows, and clean visual design.
  • Mastery of modern design and prototyping tools, specifically Figma.
  • Proven experience designing complex dashboards, data visualizations, or enterprise-grade software platforms.
  • Strong communication and presentation skills, with the ability to articulate design decisions clearly to technical and non-technical audiences.

• Nice-to-have skills:

  • Experience designing for IoT, smart buildings, industrial automation, or physical-digital hardware systems.
  • Basic understanding of front-end technologies (HTML, CSS, JavaScript) to better collaborate with engineering teams.
  • Experience conducting remote and in-person usability testing with highly specialized user groups.
  • Familiarity with accessibility standards (WCAG) for enterprise software.

Q: How technical do I need to be for this role? A: While you do not need to write code, you do need to be technically curious. Johnson Controls products interact with physical building hardware, so understanding basic concepts of how sensors, controllers, and networks function will help you design much better user experiences.

Q: What is the typical timeline for the interview process? A: The process generally takes between three to six weeks from the initial recruiter screen to the final decision. This timeline can vary depending on the location of the role and the availability of the panel interviewers.

Q: Should I expect a design test or take-home assignment? A: Some teams at Johnson Controls utilize design exercises to evaluate a candidate's hands-on design skills. If you are asked to complete a test, be sure to clarify the scope, expected time commitment, and whether the work is paid or unpaid before proceeding.

Q: What is the work culture like for designers at Johnson Controls? A: The design team operates within a highly collaborative, engineering-focused enterprise. This means you will have the opportunity to solve incredibly complex, real-world problems, but you must be proactive in advocating for the user and explaining the business value of good design.

• Understand the domain: Before your interview, familiarize yourself with Johnson Controls flagship platforms, such as OpenBlue. Understanding their focus on sustainability, energy efficiency, and smart building technology will immediately set you apart.
• Show your messy work: Do not just show polished UI screens. The interview panel wants to see your sketches, wireframes, user flows, and the mistakes you made along the way. Showing how you iterated based on feedback is highly valued.
• Prepare for the panel: The final round panel can feel intense with 5 to 6 interviewers. Keep your presentation structured, respect the time limits, and leave ample time for Q&A at the end of each project walkthrough.
• Ask smart questions: Use the end of your interviews to ask about their design system maturity, how they measure design success, and how closely the design team works with engineering.
