How long does the Leonardo interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Leonardo?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Leonardo?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

How to Pass the Leonardo Supply Chain Interview in 2026

The Leonardo DNA (TL;DR)

Leonardo values deep technical expertise in aerospace/defense systems, problem-solving skills for complex engineering challenges, and a strong commitment to safety and quality standards. They look for candidates who can collaborate effectively on large-scale projects like radar systems or helicopters.

The Leonardo Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, operations background, supply chain interest.
2
Round 2
Operations Case
End-to-end supply chain optimization, bottleneck diagnosis, network design.
3
Round 3
Forecasting & Planning
Demand planning, S&OP, inventory optimization, working with statistical and ML forecasts.
4
Round 4
Optimization
Linear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

Assuming the supplier will recover without a concrete plan.
Presenting a scenario that lacks a clear technical component.
Describing a situation where they were simply assigned a task.
Failing to involve key stakeholders from sales, marketing, operations, and finance.

Test Yourself: Real Leonardo Questions

Three real prompts pulled from our database.

Type · Supplier Risk Management

A critical supplier for a key avionics component is facing financial difficulties, potentially impacting our production schedule for a major defense contract. How would you assess and mitigate this risk?

Type · Route Optimization

Consider the logistics of delivering components to our various manufacturing sites and finished goods to customers globally. How might optimization techniques be used to improve the efficiency and reduce the carbon footprint of our transportation network?

Type · Motivation

Leonardo is a major player in aerospace and defense. What aspects of our supply chain, given our product lines (aircraft, helicopters, defense electronics), particularly interest you and why?

1
Type · Motivation
Leonardo is a major player in aerospace and defense. What aspects of our supply chain, given our product lines (aircraft, helicopters, defense electronics), particularly interest you and why?

Operations Case

2
Type · End-to-End Optimization
Imagine our helicopter division is experiencing significant delays in delivering finished aircraft due to a bottleneck in the final assembly stage. Describe how you would approach diagnosing the root cause and developing a plan to optimize the end-to-end supply chain to prevent recurrence.
3
Type · Network Design
Leonardo operates globally. If we were considering consolidating some of our component warehousing facilities to improve efficiency and reduce costs, what factors would you consider in designing the optimal network configuration?

Forecasting & Planning

4
Type · Demand Planning
Describe your experience with Sales and Operations Planning (S&OP). How would you ensure alignment between sales forecasts, production capacity, and inventory levels for Leonardo's diverse product portfolio?
5
Type · Inventory Optimization
Given the long lead times and high value of many aerospace components, how would you approach optimizing inventory levels to balance the risk of stockouts against the cost of holding excess inventory?

Optimization

6
Type · LP Intuition
Explain the basic concept of Linear Programming (LP) and how it could be applied to optimize production scheduling or resource allocation within Leonardo's manufacturing operations, without using complex mathematical notation.
7
Type · Route Optimization
Consider the logistics of delivering components to our various manufacturing sites and finished goods to customers globally. How might optimization techniques be used to improve the efficiency and reduce the carbon footprint of our transportation network?
