Olsson Software Engineer interview questions & guide 2026

Preparing for an interview at Olsson requires a shift in mindset compared to standard tech-industry preparation. Because Olsson is an engineering consulting firm, they prioritize communication, adaptability, and practical problem-solving over abstract coding riddles.

Cultural and Relational Alignment – Olsson places an immense emphasis on who you are as a person. Interviewers look for down-to-earth, authentic, and easy-to-talk-to candidates who will thrive in a collaborative, client-focused environment. Be prepared to share stories that demonstrate your humility, curiosity, and work ethic.

Domain and Systems Integration – You must show an understanding of how software interacts with physical systems. Whether your background is in computer science, controls, or electrical engineering, you need to demonstrate that you can think about the "whole system"—including hardware, software, and human operators.

Communication and Stakeholder Management – As an engineer at Olsson, you will frequently interact with professionals from other disciplines. You must be able to explain complex technical concepts in simple, clear language. Practice articulating your technical decisions and their practical business or physical impacts.

The interview process at Olsson is structured to be smooth, straightforward, and highly personal. It is designed to feel more like a mutual conversation than an interrogation. The company stays away from "trap" or "trick" questions, focusing instead on honest dialogue and mutual fit.

The process typically begins with a standard screening call with human resources to discuss your background, interest in the company, and basic qualifications. If there is a mutual fit, you will move to the next stage, which is usually a virtual or in-person panel interview. This panel typically consists of engineering managers, team leads, and potential peers. For higher-level or specialized roles, this stage may include a second, more informal conversation with regional leadership or direct managers, along with a tour of one of their campus offices.

This visual timeline illustrates the typical progression from your initial contact to the final offer. As you navigate these stages, remember that Olsson uses the panel and informal stages to assess both your technical capabilities and your alignment with their collaborative culture. Use this timeline to pace your preparation, ensuring you focus on behavioral storytelling early on and deeper domain concepts as you approach the panel stage.

To excel in the Olsson interview, you must understand the specific areas where you will be evaluated. Unlike pure software companies that focus heavily on algorithmic complexity, Olsson evaluates your ability to deliver reliable, real-world engineering solutions.

Behavioral Fit & Collaboration

At its core, Olsson is a people-first organization. They want to ensure that every new hire is someone who supports their peers, communicates transparently, and treats everyone with respect.

Be ready to go over:

• Team dynamics – How you integrate into existing workflows and support your teammates.
• Conflict resolution – How you handle differing opinions on technical designs or project directions.
• Adaptability – Your ability to handle shifting project requirements or client needs.

Example scenarios:

• "Tell me about a time you had to compromise on a technical decision to meet a project deadline."
• "Describe a situation where a teammate was not delivering on their responsibilities and how you handled it."

Controls & Systems Logic

For software and controls roles, your understanding of how software drives physical machinery, data center infrastructure, or building systems is critical.

Be ready to go over:

• Control loops and logic – Your understanding of PID loops, PLC programming, or BMS architectures.
• System redundancy – How you design software and control systems to prevent single points of failure.
• Testing and commissioning – Your approach to validating software logic before deploying it to live physical environments.
• Advanced concepts (less common) – SCADA integration, industrial network protocols (BACnet, Modbus), and high-voltage substation automation systems.

Example scenarios:

• "How would you design a control sequence to manage backup power systems in a mission-critical data center?"
• "Walk us through your process for debugging a faulty control loop in an active facility."

Conversational Problem-Solving

During the panel interview, you will likely discuss hypothetical project scenarios. The interviewers want to see how you think on your feet and how you structure your thoughts.

Be ready to go over:

• Requirement gathering – How you ask clarifying questions to understand a vague problem.
• Risk assessment – Your ability to identify potential failure points in a proposed solution.
• Client focus – How you balance technical perfection with budget, timeline, and client expectations.

Example scenarios:

• "If a client requests a feature that you know will compromise system stability, how do you handle the conversation?"
• "How do you approach modernizing an legacy control system with minimal downtime?"

As a Software Engineer or Controls Engineer at Olsson, your daily work will be highly dynamic and deeply integrated with physical engineering projects.

You will be responsible for designing, programming, and testing software and control systems for a variety of clients, particularly in high-growth sectors like data centers, federal facilities, and transport infrastructure.
