Preparation at Hexagon Ab should be grounded in your past projects and your ability to communicate your thought process. Your interviewers are not looking for rote memorization; they are looking for a systematic approach to engineering challenges.

Technical Depth – You must be able to discuss your past projects in great detail, including the specific libraries, frameworks, and mathematical foundations you utilized. Be prepared to defend your choice of architecture over alternatives.

Systems Thinking – Beyond just the model, consider the entire pipeline—from data acquisition and preprocessing to inference and post-processing. Interviewers value candidates who understand how their code interacts with the broader system architecture.

Communication Clarity – You will be presenting to teams and managers. Practice articulating your technical decisions clearly and concisely, focusing on the impact your work had on the project’s success.

The interview process at Hexagon Ab is designed to evaluate your technical proficiency, your ability to communicate complex ideas, and your fit within the team. You can expect a rigorous, multi-stage assessment that balances high-level presentations with hands-on problem solving.

The process typically begins with initial screenings to align on your experience and the team's project goals. As you progress, you will likely be asked to present your work, allowing you to showcase your expertise in a structured way. The final stages involve on-site or deep-dive technical sessions where you will solve real-world problems alongside the team.

This timeline illustrates the progression from initial screening to technical assessment and final behavioral review. Candidates should view this as a progressive funnel where each stage builds upon the last; maintain consistency in your technical narrative throughout all interactions.

Technical Proficiency

This area evaluates your mastery of computer vision fundamentals and modern machine learning practices. Strong candidates demonstrate a blend of academic rigor and practical, "in the trenches" coding skills.

Be ready to go over:

• Feature Extraction & Object Detection – Proficiency in standard and state-of-the-art architectures.
• Sensor Fusion – Understanding how to integrate data from multiple sources (e.g., LiDAR, cameras).
• Performance Optimization – Techniques for model quantization, pruning, or hardware acceleration.

Advanced concepts (less common):

• 3D point cloud processing.
• Implementation of custom loss functions for niche hardware.
• Edge-case handling in autonomous or semi-autonomous systems.

Example questions or scenarios:

• "How would you improve the accuracy of our object detection model in low-light conditions?"
• "Compare the pros and cons of two different architectures for this specific sensor input."

As a Computer Vision Engineer, your primary responsibility is the development, testing, and deployment of vision algorithms that drive Hexagon Ab products. You will work closely with hardware engineers to understand sensor constraints and with software teams to ensure your models integrate seamlessly into the core product ecosystem.

You will be expected to:

• Design and maintain robust computer vision pipelines for high-precision applications.
• Perform rigorous analysis of model performance and lead efforts to address accuracy or latency bottlenecks.
• Collaborate with the team to define project roadmaps based on technical feasibility and business requirements.
• Contribute to the technical culture by participating in code reviews and sharing knowledge on emerging research.

A competitive candidate for this role at Hexagon Ab possesses a solid academic background combined with proven industry experience in deploying computer vision solutions.

• Must-have skills: Deep proficiency in Python and C++, experience with frameworks like PyTorch or TensorFlow, and a strong grasp of linear algebra and probability.
• Nice-to-have skills: Experience with ROS (Robot Operating System), familiarity with CUDA programming, and background in 3D geometry or photogrammetry.
• Experience: Candidates typically hold a degree in Computer Science, Robotics, or a related field, with a portfolio demonstrating successful end-to-end project delivery.

Q: How long does the interview process take? A: You can generally expect a turnaround time of two weeks between major stages, though this can vary based on internal scheduling.

Q: Should I prepare for a whiteboard coding session? A: While technical problem solving is key, the focus is often on high-level architecture and system design rather than obscure algorithmic puzzles.

Q: What is the most important thing to focus on for the presentation? A: Focus on your contribution to a specific project. Be clear about the problem, your specific solution, and the measurable results.

Q: Is the team culture collaborative or independent? A: Hexagon Ab emphasizes collaboration; you will be expected to work closely with your team and communicate your findings to non-technical stakeholders effectively.

• Own your projects: Be prepared to answer "why" for every major design decision in your past work.
• Research the product: Understand the domain Hexagon Ab operates in; being able to speak to the challenges of their specific industry is a major advantage.
• Ask meaningful questions: Use your time to ask about the team's current technical hurdles or the future of their projects.
• Prepare for the demo: If you are asked to present a project, ensure your demo is polished and you can explain the underlying logic if interrupted with questions.

The Computer Vision Engineer role at Hexagon Ab is a unique opportunity to apply sophisticated technology to real-world industrial challenges. By focusing on your core technical expertise, articulating your systems-thinking approach, and demonstrating a collaborative mindset, you will be well-positioned to succeed.

Use this guide to structure your preparation, ensuring you can confidently discuss your past work and approach new problems with a logical, engineering-first mindset. You have the skills to make a significant impact—now is the time to prepare and present your best self.
