How to Pass the Maersk Software Engineer Interview in 2026

The Maersk DNA (TL;DR)

The "Global Integrator" vision at Maersk drives the assessment, seeking individuals who can articulate how their work directly contributes to seamless end-to-end logistics solutions. Interviewers often probe for examples of navigating complex, real-world trade-offs in global operations, aligning with the "All The Way Across" principle.

The Maersk Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Maersk interview outcomes, avoid these common traps:

Not considering fault tolerance and data durability.
Failing to consider case sensitivity or variations in port code representation.
Neglecting the complexity of legacy systems in a shipping environment
Underestimating the complexity of integrating data from disparate global systems.

Test Yourself: Real Maersk Questions

Three real prompts pulled from our database.

Type · Algorithmic Problem

You have a stream of vessel arrival/departure events with timestamps and port information. Design a data structure and algorithm to efficiently calculate the dwell time (time spent at port) for each vessel at every port it visits, and report the average dwell time over the last 24 hours.

Type · Ownership

Describe a time when you identified a systemic bottleneck in a logistics data pipeline or a recurring operational failure that was affecting shipment visibility. How did you advocate for the technical resources needed to fix it, and how did you measure the impact on the end-to-end supply chain?

Type · Motivation

What interests you about applying your software engineering skills to the logistics and shipping industry, specifically at Maersk?

Recruiter Screen

1
Type · Motivation
What interests you about applying your software engineering skills to the logistics and shipping industry, specifically at Maersk?
2
Type · Logistics Domain

Coding Screen

3
Type · Algorithmic Problem
Given a list of container IDs and their current locations (e.g., port, ship, warehouse), write a function to find the shortest path for a container to reach its destination port, considering only direct ship routes between major ports. Assume a graph representation of ports and routes.
4
Type · Algorithmic Problem
You have a stream of vessel arrival/departure events with timestamps and port information. Design a data structure and algorithm to efficiently calculate the dwell time (time spent at port) for each vessel at every port it visits, and report the average dwell time over the last 24 hours.

System Design

5
Type · System Design
Design a system to predict potential port congestion in the next 72 hours for Maersk's major hubs. Consider data sources, prediction models, and how the information would be surfaced to operations teams.
6
Type · System Design
Design a distributed system to manage and track millions of shipping containers globally. The system needs to provide real-time location updates, status changes (e.g., loaded, empty, damaged), and estimated time of arrival (ETA) to various stakeholders.

Onsite Coding

7
Type · Debugging
A critical service responsible for calculating Estimated Time of Arrivals (ETAs) for shipments is intermittently failing. Users report incorrect ETAs. Here's a simplified version of the code [provide code snippet]. Debug this code and explain your process.
8
Type · Algorithmic Problem
Implement a function that takes a list of historical shipment routes (sequences of port codes) and identifies the most frequent sequence of 3 ports visited consecutively. Optimize for performance on a large dataset.

Behavioral / Leadership

9
Type · Ownership
Describe a time when you identified a systemic bottleneck in a logistics data pipeline or a recurring operational failure that was affecting shipment visibility. How did you advocate for the technical resources needed to fix it, and how did you measure the impact on the end-to-end supply chain?
10
Type · Technical Conflict
We often have to balance the need for high-frequency real-time IoT sensor data from containers against the cost and latency constraints of satellite communication. Tell me about a time you had to defend a specific architectural trade-off regarding data throughput or system reliability when it conflicted with another team's requirements.
