Erith Group Software Engineer interview questions & guide 2026

Our interview process is designed to evaluate both your foundational theoretical knowledge and your practical problem-solving capabilities. While the specific questions may shift depending on the department, the following categories represent the core areas we explore during the interview.

Technical & Theoretical Knowledge

These questions assess your grasp of fundamental engineering principles and your ability to apply them in a technical context.

• How to draw a bending moment diagram.
• Explain your approach to solving structural load problems.

Preparation for Erith Group requires a balance of revisiting core engineering theory and preparing to articulate your professional history clearly. We look for candidates who can demonstrate deep technical competence while remaining adaptable to our specific project requirements.

Technical Competency – We expect you to be comfortable discussing the theoretical underpinnings of your work. Whether it is structural analysis or software implementation, be prepared to explain the "why" behind your technical decisions.

Practical Application – It is not enough to know the theory; you must demonstrate how you apply it to solve real-world problems. Be ready to walk through specific examples from your past experience where your technical choices led to a successful outcome.

Communication Skills – As a Software Engineer, you will often serve as a translator between technical requirements and project outcomes. We evaluate your ability to clearly articulate your thought process and engage with team members across different disciplines.

The interview process at Erith Group is intentionally streamlined to respect your time while ensuring we find the right fit. Typically, you will undergo a comprehensive session that includes a discussion regarding your background and a technical assessment. The pace is professional and direct, reflecting our goal-oriented culture.

This timeline illustrates the progression from your initial introduction to the final technical evaluation. Use this to structure your preparation, ensuring you have refreshed both your behavioral talking points and your technical domain knowledge before your scheduled date.

Engineering Fundamentals

Since Erith Group operates at the intersection of construction and technology, we place a high premium on your ability to apply core engineering principles. We look for candidates who can think from first principles when confronted with a technical challenge.

Be ready to go over:

• Structural and geotechnical basics – Understanding how forces interact in temporary works.
• Modeling accuracy – Ensuring that digital representations match physical reality.

As a Software Engineer, you will be embedded in teams that drive critical infrastructure projects. Your daily responsibilities include building and refining tools that assist our engineers in the field and in the office. You will frequently collaborate with structural and geotechnical experts to ensure that the software we develop meets the rigorous safety and performance standards required in the construction industry.

You will be expected to manage the full lifecycle of your tasks, from initial requirements gathering to final implementation and testing. This involves not only writing efficient code but also verifying that your solutions are robust enough to withstand the complexities of real-world construction environments.

A strong candidate for this position combines technical depth with a practical, hands-on mindset. We look for individuals who are not just comfortable with code, but who understand the physical systems that our software supports.

• Must-have skills:
  • Proficiency in core programming languages relevant to our tech stack.
  • A solid understanding of structural or geotechnical engineering theory.
  • Proven ability to apply theoretical knowledge to practical engineering challenges.
• Nice-to-have skills:
  • Experience with software development in a construction or engineering firm.
  • Familiarity with CAD or other engineering-specific software integration.

Q: How difficult are the technical tests? The technical tests are designed to be fair and practical. They focus on the core engineering knowledge required for the role, such as structural diagrams or load calculations, rather than abstract brain teasers.

Q: What is the company culture like? Erith Group values technical precision, collaboration, and a results-oriented mindset. We are a team that appreciates clear communication and a proactive approach to problem-solving.

Q: How long does the hiring process take? The process is designed to be efficient, often concluding within a few weeks of your initial interview. We aim to provide timely feedback to all candidates.

• Connect the dots: Always try to link your software skills back to engineering outcomes. We want to see that you understand the "why" behind the code.
• Be prepared for diagrams: As noted in our interview history, being able to draw and explain structural diagrams is a recurring requirement.
• Focus on the "why": When explaining your past experience, spend less time on the list of tasks and more time on the challenges you faced and how you overcame them.

Joining Erith Group as a Software Engineer offers a unique opportunity to influence the future of construction through technical innovation. By focusing on your core engineering knowledge, articulating your past experiences clearly, and demonstrating a collaborative spirit, you will be well-positioned for success.
