Cundall Consultant interview questions & guide 2026

The interview process at Cundall is designed to assess your technical competence, your ability to think on your feet, and your alignment with the company’s sustainability-focused culture. While questions vary by team and office, the following categories represent the core areas you should be prepared to address.

Industry Knowledge & Technical Domain

These questions test your understanding of current trends in the built environment, particularly your grasp of sustainability and engineering principles.

• What is net zero to you, specifically within the context of the built environment?
• Name as many sustainable building design techniques as you can think of.

Preparation at Cundall requires a balanced approach. You should be as comfortable discussing the technical details of a building simulation as you are explaining your personal motivation for joining a sustainability-focused firm.

Technical Proficiency – You must be prepared to demonstrate your core engineering or sustainability knowledge. Interviewers want to see that you can apply theory to real-world scenarios, such as optimizing cooling loads or implementing smart technology.

Problem-Solving & Adaptability – Whether you are facing a technical challenge or an in-tray exercise, focus on demonstrating a logical, structured thought process. If you encounter a question where you don't know the exact answer, explain how you would go about finding the solution.

Communication & Culture Fit – Cundall values individuals who are approachable, collaborative, and genuinely passionate about sustainability. Use your interviews to show you can communicate complex ideas clearly and that you understand the firm’s commitment to the environment.

The hiring process at Cundall is generally characterized by a professional yet relaxed atmosphere, often described as an informal discussion rather than a rigid interrogation. You should expect a streamlined process, usually consisting of one or two main stages. The firm prioritizes getting to know the individual, so expect interviewers to focus on your personality and your ability to work within their team-oriented culture.

The process often begins with a screen, followed by a more formal interview or a series of assessments. In some regions or specific roles, you may encounter group exercises or in-tray tasks designed to test your real-time problem-solving skills. The overall tone is one of respect and transparency; interviewers are often helpful, willing to answer your questions about the role, and generally provide feedback in a timely manner.

The timeline shows a clear progression from initial screening to more in-depth technical or situational assessments. Candidates should use this structure to manage their energy; while the process is often described as "straightforward," the technical portions require focused mental preparation. Expect to be challenged, but view the interaction as a two-way dialogue rather than a one-sided assessment.

Sustainability & Net Zero

This is the cornerstone of Cundall’s reputation. You will be evaluated on your ability to apply sustainability principles to practical building challenges.

Be ready to go over:

• Net Zero Principles – Defining what net zero means for the built environment.
• Sustainable Design Techniques – Being able to list and explain passive and active design strategies.
