Sargent & Lundy UX/UI Designer interview questions & guide 2026

While interview experiences can vary by office and team, the following questions reflect the patterns observed in the Sargent & Lundy hiring process. Treat these as a baseline for understanding the interviewers' focus on your technical foundation and your ability to navigate professional challenges.

Behavioral and Professional Alignment

These questions assess your communication style, your adaptability in a team environment, and your overall fit for the company’s professional culture.

• Why are you looking to leave your current job?
• Tell us about a challenging experience in your previous position and how it was resolved.

Preparation for a UX/UI Designer role at Sargent & Lundy should move beyond simple portfolio review. You must be prepared to articulate not just what you designed, but why your design decisions were the correct ones for a complex, technical user base.

Technical Competency – You must be able to speak fluently about your design process, particularly as it relates to technical or engineering-heavy interfaces. Interviewers look for evidence that you can translate complex data into accessible user flows. Be ready to walk through specific projects that demonstrate your technical proficiency.

Collaborative Problem-Solving – Sargent & Lundy values professionals who can navigate multi-disciplinary teams. You will be evaluated on your ability to articulate how you resolve conflicts, how you handle feedback from non-design stakeholders, and how you adapt your communication style to bridge the gap between technical and non-technical team members.

Professional Maturity – The interviewers are assessing your ability to operate within a formal, established organization. Demonstrate your reliability, your research-driven approach to design, and your genuine interest in the energy and infrastructure sectors.

The interview process at Sargent & Lundy is typically structured, efficient, and direct. You can expect a multi-stage approach that begins with a phone screen to assess your background and interest, followed by a more comprehensive in-person or virtual interview series. These later stages often involve multiple stakeholders—ranging from peers to senior management—to ensure a holistic evaluation of your skills and cultural alignment.

The atmosphere is often described as professional and conversational. Interviewers are generally interested in a deep, cross-disciplinary dialogue rather than a series of rapid-fire technical quizzes. Your goal is to engage in a two-way conversation that showcases both your design expertise and your ability to function as a collaborative member of a technical enterprise.

This visual timeline illustrates the progression from initial screening to final interview rounds. Candidates should note that the process is designed to be rigorous but consistent; use this to pace your preparation, ensuring you have enough time to research the specific office location and the types of projects they prioritize.

Design Process and Methodology

Understanding how you reach a solution is often more important than the final visual output. Interviewers want to see a structured approach to problem-solving.

Be ready to go over:

• User Research – How you define user needs in a technical context.
• Iterative Prototyping – How you handle feedback and refine designs under constraint.

As a UX/UI Designer, you will be responsible for the full lifecycle of design initiatives within your assigned team. This includes gathering requirements from project engineers, creating wireframes and high-fidelity prototypes, and conducting design reviews with key stakeholders. You will often act as the "user advocate" in meetings, ensuring that the functionality of complex systems remains intuitive and efficient.

Collaboration is central to this role. You will work closely with software engineers to ensure the feasibility of your designs and with project managers to align your work with broader business goals. Typical projects may involve the redesign of internal tools, the creation of client-facing dashboards, or the improvement of interface controls for power systems.

A strong candidate for this position combines a solid technical foundation with the soft skills necessary to thrive in a consulting environment.

• Must-have skills – Proficiency in industry-standard design tools (e.g., Figma, Adobe Creative Suite), a deep understanding of UI principles, and the ability to articulate design decisions to non-designers.
• Experience level – A proven track record in professional design roles, ideally with exposure to complex systems, data-heavy applications, or engineering environments.
• Soft skills – Exceptional communication skills, a collaborative mindset, and the ability to remain composed and articulate during multi-interviewer sessions.

Q: How long does the entire interview process take? The timeline can vary, but generally, expect a few weeks from the initial screening to a final decision. While some processes move quickly, others may require a longer internal review period.

Q: What is the best way to prepare for the conversational aspect of the interview? Focus on being yourself and doing your research. Use your past experiences to tell clear, concise stories about how you solved problems, and be prepared to discuss the "why" behind your design choices.

Q: Is there a design test or portfolio review? While not every candidate reports a formal design test, you should be prepared to walk through your portfolio in detail. Focus on projects that highlight your ability to handle complexity and work with cross-functional teams.

Q: How can I stand out to the interviewers? Show genuine interest in the work Sargent & Lundy does. Understanding the nuances of the energy and power industry will set you apart from candidates who only focus on general design skills.

• Research the company's projects: Familiarize yourself with the type of work Sargent & Lundy does in the power and energy sector.
• Practice your "Why": For every project in your portfolio, be prepared to explain the business or user problem you were solving and how your design addressed it.
• Prepare questions for them: Asking thoughtful questions about the team's current challenges or the company's design culture demonstrates your serious intent.
• Mind your communication: Because you will be working with diverse teams, practice explaining design concepts in simple, clear terms that a non-designer would understand.

The UX/UI Designer role at Sargent & Lundy is an excellent opportunity to apply your design expertise to high-impact, complex infrastructure projects. By focusing on your ability to articulate your process, demonstrating your understanding of technical environments, and preparing for a multi-stakeholder interview, you can significantly improve your standing.
