• Object-Oriented Programming (OOP) – Demonstrating clean code principles, design patterns, and effective inheritance versus composition.

Example scenarios:

• "Given a database schema containing shipment orders and warehouse locations, write a SQL query to find the top three most active transit hubs."
• "Implement an algorithm to find the shortest path for a delivery vehicle given a set of geographical coordinates and constraints."

Behavioral & Scenario-Based Leadership

Technical skills alone are not enough to succeed at Maersk. The company seeks engineers who communicate effectively, handle ambiguity gracefully, and align with their collaborative culture.

Be ready to go over:

• Pair Programming Adaptability – Demonstrating your comfort with continuous collaboration and shared code ownership.
• Conflict Resolution – Navigating healthy technical disagreements within a team setting.
• Domain Engagement – Showing a proactive interest in learning about Supply Chain Management (SCM) and enterprise landscapes.

Example scenarios:

• "Tell me about a time you had to deliver a feature with incomplete requirements. How did you proceed?"
