How to Pass the Saipem Software Engineer Interview in 2026

The Saipem DNA (TL;DR)

Saipem's project execution focus drives interviewers to assess candidates' practical experience in complex engineering and construction. They seek individuals who can demonstrate successful delivery of large-scale energy solutions, aligning with the "Strategy and Objectives Financial" principle by ensuring technical viability and economic efficiency.

The Saipem Interview Loop

Your onsite loop will typically consist of 5 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, role fit, logistics.
  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard, debugging, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership
    Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

  • Giving a generic answer about 'the energy industry' without mentioning Saipem's specific areas.
  • Failing to identify the root cause of the bug, instead making superficial changes.
  • Describing a simple task as 'complex' without specific examples of technical hurdles.
  • Describing a situation where they simply followed orders without offering their perspective.

Test Yourself: Real Saipem Questions

Three real prompts pulled from our database.

Type · motivation

Saipem is a global leader in energy infrastructure and services. What specifically about Saipem's work in offshore wind, subsea engineering, or carbon capture technologies excites you and aligns with your career goals as a software engineer?

Type · system design

Design a distributed system for processing and analyzing large volumes of seismic survey data to identify potential oil and gas reservoirs. Consider data storage, parallel processing, data quality checks, and visualization of results for geoscientists.

Type · past experience

Describe a time you had to work with a complex, legacy codebase at Saipem or a previous company. What were the biggest challenges, and how did you approach understanding, modifying, or improving it?

  1. 2

    Type · algorithmic

    Given a dataset of offshore platform sensor readings (timestamp, sensor_id, value), write a function to detect anomalies. An anomaly is defined as a reading that deviates by more than 3 standard deviations from the rolling average of the past hour for that specific sensor. Return a list of (timestamp, sensor_id) for detected anomalies.
  2. 3

    Type · algorithmic

    You are given a list of subsea pipeline segments, each with a start point, end point, and a material type. Write a function to determine if any two segments intersect, considering they are straight lines in 3D space. Assume segments are defined by their start and end coordinates.

  1. 4

    Type · system design

    Design a real-time monitoring system for a fleet of offshore drilling rigs. The system should collect data (pressure, temperature, vibration, location) from thousands of sensors, process it, detect potential equipment failures or safety hazards, and alert relevant personnel. Consider data volume, latency, reliability, and scalability.
  2. 5

    Type · system design

    Design a system to optimize the scheduling of maintenance for subsea remotely operated vehicles (ROVs). The system should consider ROV availability, maintenance crew schedules, spare parts inventory, and the urgency of maintenance tasks based on operational impact. Aim for minimizing downtime and operational disruption.

  1. 6

    Type · algorithmic

    Implement a function that takes a 2D grid representing a subsea terrain (height map) and calculates the amount of water trapped after rainfall. Water is trapped if it's surrounded by higher terrain on all sides (including edges). Assume water flows downwards.
  2. 7

    Type · debugging

    Here is a Python script intended to calculate the total CO2 emissions from a fleet of vessels based on their fuel consumption logs. It seems to be producing incorrect results for certain periods. Please debug and fix it. [Provide a buggy script that has issues like incorrect date parsing, off-by-one errors in summation, or incorrect emission factor application].
