The Oxa DNA (TL;DR)
The technical deep-dive round at Oxa deeply evaluates a candidate's ability to apply theoretical knowledge to real-world autonomous vehicle challenges, especially within Industrial Mobility Automation. They seek individuals who can articulate the trade-offs in designing robust, safe systems for complex environments like Heathrow Airport, demonstrating a clear understanding of system constraints.
The Oxa Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard problems, reasoning about defects, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Oxa interview outcomes, avoid these common traps:
- Not designing for fault tolerance and ensuring the system remains available.
- Suggesting a solution that ignores the operational constraints of industrial mobility
- Sorting the entire list of objects by distance, which is inefficient if N is small.
- Choosing a monolithic architecture instead of a scalable, distributed one.
Test Yourself: Real Oxa Questions
Three real prompts pulled from our database.
Type · Coding
Write a robust C++ class to represent a 3D point, including methods for translation, rotation, and calculating the distance to another point. Ensure proper handling of floating-point precision issues and include unit tests.
Type · Algorithmic
You are given a large dataset of historical driving logs. Design a data structure and algorithm to efficiently query for all instances where a specific type of maneuver (e.g., sudden braking, sharp turn) occurred within a given geographic area and time window.

9 of 13 questions shown
1
Recruiter Screen
1- 1
Type · Motivation
What interests you about working on autonomous driving technology at Oxa, and how do you see your skills contributing to our mission?
2
Coding Screen
3- 2
Type · Algorithmic
Given a stream of sensor data (e.g., lidar points, camera frames) and a set of detected objects with their bounding boxes and velocities, design an algorithm to predict the future trajectory of each object for the next 5 seconds. Assume a simplified physics model. - 3
Type · Algorithmic
Implement a function that takes a 2D grid representing a map with obstacles and a starting point, and returns the shortest path to a target point. The vehicle can move up, down, left, right, and diagonally, but cannot move through obstacles. Consider different movement costs for cardinal vs. diagonal directions. - + 1 more questions in this round (sign up to unlock)

Design a real-time system for detecting and reporting 'near-miss' incidents between autonomous vehicles and other road users (pedestrians, cyclists, other vehicles). Consider data ingestion, processing, and alerting. - 5
Type · System Design
Design a system to manage and serve high-definition map updates to a fleet of autonomous vehicles. Consider aspects like data storage, distribution, versioning, and ensuring data integrity. - + 2 more questions in this round (sign up to unlock)

Onsite Coding
2- 6
Type · Coding
Write a robust C++ class to represent a 3D point, including methods for translation, rotation, and calculating the distance to another point. Ensure proper handling of floating-point precision issues and include unit tests. - 7
Type · Coding
Implement a function to efficiently find the N closest objects to a given reference point from a large, unsorted list of objects, each with a 3D position. Optimize for performance, especially when N is much smaller than the total number of objects.
5
Behavioral / Leadership
3- 8
Type · Behavioral
Tell me about a time you had to make a significant technical decision with incomplete information. How did you approach it, what was the outcome, and what did you learn? - 9
Type · Behavioral
Describe a complex bug you encountered in a critical system, like perception or control. Walk me through your process of identifying, debugging, and resolving it. What steps did you take to prevent recurrence? - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the Oxa 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 Oxa?
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 Oxa?
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.
