How to Pass the Volocopter Software Engineer Interview in 2026

The Volocopter DNA (TL;DR)

Volocopter seeks individuals who demonstrate meticulous engineering rigor and a deep understanding of safety-critical systems, essential for their VoloCity and VoloConnect aircraft development. Interviewers often assess candidates' ability to navigate complex regulatory frameworks like EASA certification while driving innovation.

The Volocopter 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 Volocopter interview outcomes, avoid these common traps:

  • Not considering the streaming nature of the data and proposing an batch-processing solution.
  • Proposing fixes without explaining the root cause.
  • Giving a generic answer about wanting to work in aerospace without specific connection to eVTOL or Volocopter.
  • Poor variable naming and lack of comments, making the code hard to understand.

Test Yourself: Real Volocopter Questions

Three real prompts pulled from our database.

Type · ownership

At Volocopter, we deal with complex hardware-software integration where failures can be catastrophic. Tell me about a time you identified a latent bug or a systemic flaw in a flight-critical module that was not part of your direct task list. How did you validate the severity of the issue and ensure it was addressed before it reached the testing or production phase?

Type · motivation

What interests you specifically about working on software for electric vertical take-off and landing (eVTOL) aircraft, and how do you see your skills contributing to Volocopter's mission?

Type · debugging

A critical component in our flight control system is experiencing intermittent failures. The logs show occasional 'attitude control deviation' errors. Analyze the provided (simplified) code snippet for the attitude control module and identify potential bugs or race conditions that could lead to such errors, and suggest fixes.

  1. 2

    Type · data-structures

    Given a stream of sensor data from an aircraft, design a system to detect anomalies that could indicate a potential system failure. You need to process this data efficiently and identify deviations from normal operating parameters. Assume sensor data is a list of tuples (timestamp, sensor_id, value).
  2. 3

    Type · algorithms

    Imagine you are optimizing flight path calculations for a fleet of eVTOLs. You have a set of potential landing zones, each with a cost (e.g., time, energy). Given a starting point and a maximum flight time, find the optimal sequence of landing zones to visit to maximize a certain objective (e.g., minimize total energy consumption while visiting at least K zones).

  1. 4

    Type · distributed-systems

    Design a distributed system for managing the charging infrastructure for Volocopter's fleet. Consider aspects like real-time battery status monitoring, scheduling charging sessions, load balancing across charging stations, and integration with air traffic control for optimal fleet deployment.
  2. 5

    Type · api-design

    Design the API for a system that allows ground crew to remotely monitor and control basic functions of an eVTOL during pre-flight checks and post-flight diagnostics. Consider operations like checking battery levels, system status, activating diagnostic modes, and receiving alerts.

  1. 6

    Type · algorithms

    Implement a function to calculate the shortest path between two points on a 3D map, considering altitude changes and potential no-fly zones. The map can be represented as a grid or a graph. Pay close attention to edge cases and performance.
  2. 7

    Type · data-structures

    Design and implement a data structure to efficiently store and query the trajectory of multiple eVTOLs over time. The structure should support adding new trajectory points, retrieving the trajectory of a specific aircraft within a time range, and finding aircraft that were within a certain geographical area at a given time.

  1. 8

    Type · conflict-resolution

    When developing safety-critical flight control software, engineers often clash between implementing a feature for operational efficiency and adhering to strict EASA certification requirements. Describe a situation where you advocated for a specific technical constraint or safety buffer against pressure to prioritize performance or delivery speed. How did you balance the engineering rigor with the project timeline?
  2. 9

    Type · ownership

    At Volocopter, we deal with complex hardware-software integration where failures can be catastrophic. Tell me about a time you identified a latent bug or a systemic flaw in a flight-critical module that was not part of your direct task list.
