The interview journey for a UX/UI Designer at Molex is designed to evaluate both your tactical design execution and your ability to thrive in a collaborative engineering culture. Depending on your region and the specific business unit, the process typically moves at a steady, professional pace, blending remote video discussions with structured technical evaluations. Interviewers value authenticity, clear communication, and a grounded personality that can inspire confidence across multidisciplinary teams.

Expect a multi-stage evaluation that begins with an initial screening call to align on experience, compensation, and baseline qualifications. From there, you will advance to technical and managerial discussions conducted via virtual meeting platforms, where you will dive deep into your portfolio, problem-solving methodologies, and past projects. Some locations may incorporate rapid-fire questioning or collaborative review sessions to test how quickly you think on your feet. Throughout the process, the emphasis remains on your ability to defend design choices while remaining adaptable to engineering realities.

This visual timeline illustrates the typical progression from initial recruiter screening through technical and managerial evaluations, culminating in final HR alignment. Candidates should use this roadmap to pace their preparation, ensuring they are ready to pivot from high-level portfolio overviews to detailed situational problem-solving. Keep in mind that exact interview formats can vary slightly by region and team seniority, so remain flexible and communicate proactively with your recruiting coordinator.

Portfolio and Design Execution

• This area assesses the quality, depth, and practical impact of your past design work. Interviewers look for clean execution, strong information architecture, and clear evidence of user-centered decision-making. Strong performance means you can articulate the business and user problems you solved, rather than just showing final aesthetic outputs.

Be ready to go over:

• Wireframing and Prototyping – How you build low and high-fidelity artifacts to test concepts.
• Information Architecture – How you organize complex data and navigational structures for technical users.

As a UX/UI Designer at Molex, your daily routine revolves around transforming complex technical specifications into intuitive, elegant digital and physical touchpoints. You will take ownership of the end-to-end design lifecycle, starting from initial user research and wireframing all the way to high-fidelity prototyping and design handoff. Your work ensures that users—whether configuring industrial automation tools or navigating enterprise applications—can interact with Molex technology seamlessly and efficiently.

Collaboration is a cornerstone of your daily responsibilities. You will work side-by-side with software developers, mechanical engineers, and product managers to understand the deep technical realities underlying every product. By participating in cross-functional design reviews and engineering syncs, you ensure that user needs remain at the center of product development. You will also drive usability testing sessions, gathering direct feedback from operators and clients to continuously refine and improve existing interface ecosystems.

Beyond individual project execution, you will help shape the broader design culture across the organization. This includes contributing to design systems, establishing component libraries, and advocating for accessibility and ergonomic best practices. You will manage multiple design threads simultaneously, balancing long-term strategic interface overhauls with rapid tactical updates to support ongoing engineering releases.

Meeting the competitive threshold for a UX/UI Designer at Molex requires a balanced portfolio demonstrating both exceptional visual craft and a strong grasp of technical product design. Interviewers will look closely at your foundational design knowledge, your technical toolkit, and your ability to collaborate within industrial or enterprise environments.

• Must-have skills – Proficiency in industry-standard design and prototyping tools (such as Figma, Adobe XD, or Sketch), a robust portfolio showcasing end-to-end product design processes, strong wireframing and user research capabilities, and demonstrated experience collaborating directly with software or hardware engineering teams.
• Nice-to-have skills – Experience designing interfaces for industrial automation, IoT devices, or enterprise dashboard software; familiarity with basic engineering constraints, manufacturing workflows, or hardware-software integration; and prior exposure to agile development environments.
• Experience level – Typically requires several years of professional product design experience, with a proven track record of shipping successful digital or physical-digital hybrid products from conception to completion.
• Soft skills – Exceptional communication and stakeholder management abilities, resilience under pressure, openness to cross-functional critique, and the confidence to advocate for the user across multidisciplinary teams.
