How to Pass the Avio Software Engineer Interview in 2026

The Avio DNA (TL;DR)

Avio's 'Ready to Fly' ethos drives interview assessments, seeking individuals who demonstrate meticulous technical execution and adherence to aerospace standards. Interviewers evaluate candidates' capacity for rigorous analysis and their contributions to successful project delivery, often through examples of complex system integration.

The Avio 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 Avio interview outcomes, avoid these common traps:

Complaining about the legacy code without offering solutions or learning.
Oversimplified physics model leading to unrealistic simulation.
Poor handling of aircraft priorities or complex scheduling rules.
Failing to handle edge cases like missing data points or invalid coordinates.

Test Yourself: Real Avio Questions

Three real prompts pulled from our database.

Type · system-design

Design a distributed system for real-time monitoring of a fleet of commercial aircraft. The system should collect telemetry data (location, altitude, engine status, etc.), process it, and provide alerts for critical events (e.g., engine malfunction, deviation from flight path). Consider scalability, fault tolerance, and data security.

Type · coding

Write a function to simulate the deployment of a parachute system. The function should take current altitude, descent rate, and wind conditions as input, and determine the optimal deployment time to ensure a safe landing. Consider factors like parachute drag and air density.

Type · motivation

What interests you about working at Avio, specifically within the aerospace industry, and how do you see your software engineering skills contributing to our mission of advancing aerospace technology?

Recruiter Screen

1
Type · motivation
What interests you about working at Avio, specifically within the aerospace industry, and how do you see your software engineering skills contributing to our mission of advancing aerospace technology?

Coding Screen

2
Type · algorithm
Given a dataset of flight trajectories (sequences of GPS coordinates and timestamps), write a function to detect potential anomalies such as sudden altitude changes or deviations from planned routes. Assume the dataset is too large to fit into memory.
3
Type · algorithm
Implement a function that simulates the behavior of a simplified air traffic control system. It needs to assign runways to incoming aircraft based on their type (e.g., commercial, cargo, private) and urgency, ensuring no two aircraft use the same runway simultaneously. Optimize for minimal waiting time.

System Design

4
Type · system-design
Design a distributed system for real-time monitoring of a fleet of commercial aircraft. The system should collect telemetry data (location, altitude, engine status, etc.), process it, and provide alerts for critical events (e.g., engine malfunction, deviation from flight path). Consider scalability, fault tolerance, and data security.
5
Type · system-design
Design a system to manage and optimize the maintenance schedules for Avio's aircraft components. The system should ingest data from various sources (usage logs, sensor data, manufacturer recommendations) and suggest optimal times for maintenance to minimize downtime and costs.

Onsite Coding

6
Type · coding
Implement a class that models a simplified aircraft navigation system. It should be able to calculate distances and bearings between waypoints using Haversine formula, and manage a sequence of waypoints for a flight plan. Ensure the implementation is robust and handles potential floating-point inaccuracies.
7
Type · debugging
Here is a piece of code intended to calculate fuel consumption for a flight based on various parameters (distance, speed, altitude, aircraft weight). It's producing incorrect results for certain inputs. Debug and fix the code, explaining your thought process.

Behavioral / Leadership

8
Type · behavioral
Tell me about a time you had to work with a complex, legacy codebase. What challenges did you face, and how did you approach understanding and modifying it?
9
Type · behavioral
Describe a situation where you disagreed with a technical decision made by your team or lead. How did you handle the disagreement, and what was the outcome?
