So Energy Software Engineer interview questions & guide 2026

Our interview process is designed to evaluate both your technical proficiency and your alignment with our collaborative, growth-oriented culture. While questions may vary based on the team and seniority, the following categories represent the core areas we focus on during our assessments.

Technical and Domain Expertise

These questions test your practical knowledge of software architecture and your ability to navigate real-world engineering challenges.

• How do you manage API versioning?
• What are some of the technologies you like, and why?

Preparation at So Energy should focus on demonstrating both your technical depth and your ability to communicate your thought process clearly. We are looking for engineers who are not only capable of writing clean code but who also understand the "why" behind their architectural decisions.

Technical Competence – We look for evidence that you can navigate modern backend environments. Be prepared to discuss your experience with microservices, messaging, and language-specific best practices in Java or Kotlin.

Problem-Solving and Initiative – We value engineers who "leave things better than they found them." Use your interview to highlight instances where you identified a problem, proposed a solution, and saw it through to completion.

Communication and Collaboration – Since we work in highly collaborative, cross-functional teams, your ability to explain complex technical concepts to non-technical stakeholders or coach peers is critical. Be ready to discuss your working practices and how you navigate ambiguity.

The interview process at So Energy is designed to be efficient, professional, and transparent. We prioritize a quick turnaround time and maintain clear communication from the initial screening through to the final decision. You can expect a process that balances technical assessment with meaningful conversations about your professional goals and cultural alignment.

This timeline illustrates the progression from your initial recruiter screen to the final behavioral and technical assessments. Candidates should view this as a structured journey: the initial stages are about alignment, while the later stages focus on your hands-on technical skills and team compatibility. Use this structure to pace your preparation, ensuring you are ready for both high-level discussions and deep-dive technical challenges.

Technical Assessment

We use tools like CyberDojo to evaluate your coding proficiency in a real-time, pair-programming environment. This allows us to see how you think, how you handle syntax, and how you approach problem-solving in a collaborative setting.

Be ready to go over:

• Pair Programming – Demonstrating your ability to communicate while coding.
• Problem Decomposition – Breaking down complex tasks into manageable, testable units.

As a Software Engineer, your day-to-day work revolves around building and maintaining high-impact services. You will be expected to contribute to the full software development lifecycle, from initial design discussions to deployment and monitoring. You will work closely with Software Architects, Engineering Managers, and other developers to ensure that our technical roadmap is aligned with our business goals.

Collaboration is at the heart of what we do. You will often engage in pair programming, participate in code reviews, and contribute to team-wide initiatives aimed at improving our development practices. We encourage our engineers to take ownership of their work, which means you will be expected to identify bottlenecks, propose architectural improvements, and participate in the coaching of peers to raise the overall technical bar of the team.

We are looking for engineers who are comfortable with the challenges of a scaling, distributed system. While we value specific technical skills, we place an equal premium on your ability to work well within a team and your commitment to continuous improvement.

• Must-have skills – Strong proficiency in Java or Kotlin, experience with microservices architectures, and a solid understanding of messaging systems.
• Nice-to-have skills – Experience with cloud-native development, familiarity with modern CI/CD pipelines, and a background in energy or utility sectors.
• Experience level – We value candidates who have a track record of taking initiative, regardless of their total years of experience. Seniority is measured by your ability to impact the team and mentor others.

Q: How long does the entire interview process typically take? The process is designed to be fast. From the initial recruiter screen to the final interview, we aim to keep the momentum high, often completing the stages within a few weeks.

Q: How should I prepare for the pair programming session? Focus on communicating your thought process aloud. We are less interested in perfect syntax and more interested in how you approach the problem and collaborate with your partner.

Q: What is the culture like at So Energy? Our culture is defined by transparency and a desire to improve. We are a group of people who are not afraid to admit mistakes and work together to fix them, making it a great environment for engineers who want to make a real impact.

• Own your narrative: Be prepared to talk about your past experiences, specifically instances where you made a system better or handled a difficult challenge.
• Ask questions: We value candidates who are inquisitive. Ask your interviewers about their challenges, the team's goals, and how they view the company's trajectory.
• Be direct: Our team appreciates honesty. If you don't know the answer to a technical question, explain how you would go about finding it rather than guessing.
• Embrace feedback: We are a company that prides itself on constant improvement. Showing that you are coachable and open to constructive feedback is a major green flag.

The Software Engineer role at So Energy is a unique opportunity to apply your technical skills in an environment that prioritizes growth, transparency, and real-world impact. By focusing on your ability to articulate your technical design decisions, demonstrating a collaborative spirit during pair programming, and showing a genuine commitment to improving our systems, you will be well-positioned for success.
