Be ready to go over:

• Quantitative Aptitude – Solving logical, mathematical, and statistical problems quickly and accurately.
• Data Interpretation – Analyzing charts, tables, and numerical datasets to draw logical conclusions.
• Algorithmic Efficiency – Evaluating the time and space complexity (Big O notation) of your code and optimizing performance bottleneck areas.

Example scenarios:

• "Given a specific mathematical formula used to calculate energy efficiency, write an optimized algorithm to apply this formula across a dataset of millions of rows."
• "Complete a 30-minute quantitative test consisting of complex logical reasoning and mathematical word problems."

As a Software Engineer at Rystad Energy, you will be embedded in a highly collaborative environment where software engineering directly drives business value. Your day-to-day work will involve a mix of system design, data pipeline development, and platform optimization.

• System Architecture & API Development: You will design, build, and maintain high-performance API services that deliver complex energy data and analytics to clients globally. This involves writing clean, production-grade Python code and ensuring high availability and low latency.
• Data Ingestion & Pipeline Engineering: You will build robust, automated data pipelines to harvest, process, and clean massive datasets from diverse external sources. This includes developing resilient web scrapers and structuring efficient ETL workflows.
• Database Management: You will design and optimize relational and non-relational database schemas, ensuring that data is stored securely, structured logically, and accessible via highly optimized queries.
• Cross-Functional Collaboration: You will work closely with energy analysts, data scientists, and product managers to understand domain-specific requirements and translate them into scalable software solutions.
• Code Quality & Mentorship: You will participate in rigorous code reviews, contribute to internal engineering standards, and help maintain a clean, well-documented codebase.

To be competitive for the Software Engineer position at Rystad Energy, you should possess a strong foundational background in computer science, coupled with practical experience in data-intensive software development.

Technical Skills

• Must-have skills:
  • Strong proficiency in Python and deep knowledge of its standard libraries and object-oriented programming (OOP) paradigms.
  • Practical experience building and consuming RESTful APIs.
  • Solid understanding of database design and optimization using SQL (e.g., PostgreSQL, SQL Server) or NoSQL databases.
  • Experience with web scraping libraries and frameworks, particularly Scrapy, BeautifulSoup, or Selenium.
• Nice-to-have skills:
  • Familiarity with cloud platforms such as AWS or Azure.
  • Experience with containerization tools like Docker and CI/CD pipelines.
  • Exposure to front-end technologies (e.g., React) or data visualization libraries.

Experience & Soft Skills

• Experience Level: Typically 2+ years of professional software engineering experience, preferably in data-heavy environments, financial technology, or business intelligence.
• Analytical Mindset: Strong quantitative, logical, and problem-solving skills, with a keen eye for data quality and system performance.
• Communication: Excellent verbal and written communication skills, with the ability to explain complex technical concepts clearly to both technical and non-technical stakeholders.
• Adaptability: Comfort working in a fast-paced environment and managing ambiguous requirements as business needs evolve.

Q: How technical is the interview process at Rystad Energy? A: The process is highly technical and practical. You will be evaluated on your live coding ability, your understanding of core computer science fundamentals (like OOP and API design), and your practical experience with databases and web scraping.

Q: What is the company culture like for Software Engineers? A: The culture is highly collaborative, professional, and intellectually stimulating. Engineers work closely with domain experts and analysts, which provides a unique opportunity to learn about the global energy transition while building cutting-edge software.

Q: How should I prepare for the quantitative and case study rounds? A: For the quantitative rounds, focus on speed and accuracy by practicing timed logical reasoning puzzles. For the case study rounds, practice designing complete data pipelines—from web scraping with Scrapy to structuring database tables—and be ready to explain your architectural choices.

Q: Is there flexibility in terms of remote or hybrid work? A: Rystad Energy generally operates on a hybrid work model, blending the collaboration benefits of in-office teamwork with the flexibility of working from home. Specific arrangements can vary depending on the office location and team requirements.

• Prioritize OOP Concepts: Do not just memorize the definitions of the four pillars of OOP. Be ready to write clean, modular Python classes that actively demonstrate inheritance, encapsulation, polymorphism, and abstraction during your live coding rounds.
• Be Fast and Structured in Case Studies: During case study rounds, time is of the essence. Structure your thoughts immediately, communicate your plan to the interviewer, and build a working baseline before diving into micro-optimizations.

• Master API Design Principles: Spend time reviewing API design best practices. Be prepared to discuss how you would handle pagination, versioning, error handling, and security for a high-traffic endpoint.
• Brush Up on Web Scraping: If you haven't used Scrapy recently, spend some time building a basic spider. Understand how to handle pipelines, middlewares, and selectors, as these are highly relevant to Rystad Energy's core data gathering operations.
• Ask Clarifying Questions: Before writing any code or proposing a system design, ensure you fully understand the constraints. Ask about data volume, expected latency, user patterns, and edge cases. This demonstrates structured, senior-level engineering behavior.

The Software Engineer role at Rystad Energy is an exceptional opportunity for developers who want to apply their technical skills to meaningful, global-scale data challenges. By building the systems that ingest, structure, and serve critical energy intelligence, you will play a direct role in helping organizations navigate the complex global energy landscape and transition.

To maximize your chances of success, focus your preparation on core Python mastery, clean object-oriented design, robust API architecture, and practical web scraping frameworks. Approach your interviews with a structured, analytical mindset, and be ready to collaborate closely with your interviewers to solve complex technical problems.
