How to Pass the Orsted Software Engineer Interview in 2026
The Orsted DNA (TL;DR)
Orsted interviews for candidates who can navigate complex energy projects, balancing technical depth with commercial acumen. They look for individuals who can articulate trade-offs and demonstrate impact on offshore wind farms or green hydrogen initiatives.
The Orsted Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Orsted interview outcomes, avoid these common traps:
- Inefficiently recalculating the average on every new data point.
- Designing a monolithic gateway instead of a flexible, extensible one.
- Ignoring network latency and reliability issues in a distributed system.
- Focusing on superficial errors instead of the root cause (e.g., race conditions, data corruption).
Test Yourself: Real Orsted Questions
Three real prompts pulled from our database.
Type · Algorithm
You are given sensor data streams from various renewable energy sources (wind turbines, solar panels). Design a data structure and algorithm to efficiently calculate the real-time average power output for a specific region, considering potential data loss or out-of-order arrivals.
Type · Debugging
A deployed service responsible for aggregating energy production data from multiple sources is intermittently failing, reporting incorrect totals. Debug this issue using provided logs and code snippets.

Recruiter Screen
1- 1
Type · Motivation
What interests you about working at Orsted, specifically within our mission to accelerate the transition to renewable energy?
2
Coding Screen
3- 2
Type · Algorithm
Given a list of offshore wind farm locations and their power generation capacities, write a function to find the subset of farms that maximizes total power output while staying within a given budget for maintenance. This is a variation of the knapsack problem. - 3
Type · Algorithm

3
System Design
3- 4
Type · System Design
Design a system to monitor and control a distributed network of smart grid devices (e.g., smart meters, EV chargers) to optimize energy distribution and minimize grid load during peak hours. - 5
Type · System Design
Design a system for collecting, processing, and analyzing large volumes of real-time data from thousands of offshore wind turbines. The system should support anomaly detection, predictive maintenance, and performance reporting. - + 1 more questions in this round (sign up to unlock)
