The Nothing DNA (TL;DR)
The Nothing 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, debugging, 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 Nothing interview outcomes, avoid these common traps:
- Incorrectly handling the representation of preference combinations (e.g., treating ['a', 'b'] as different from ['b', 'a']).
- Not mentioning the positive impact or learning from the experience.
- Focusing only on software without considering potential hardware interactions or misconfigurations.
- Making superficial changes without addressing the underlying structural issues.

9 of 23 questions shown
Recruiter Screen
1- 1
Type · Motivation
What interests you about working at Nothing, specifically in a software engineering role, compared to other tech companies?
Coding Screen
3- 2
Type · Data Structures & Algorithms
Given a stream of user interactions with Nothing products (e.g., button presses, screen touches, audio playback events), design a system to detect and report anomalous patterns in real-time. Assume events have timestamps and user IDs. What data structures would you use to efficiently track recent activity per user? - 3
Type · Algorithms
Implement a function that takes a list of audio playback events (each with a start time, end time, and device ID) and returns the total unique listening time per device, ensuring no overlapping intervals are double-counted. For example, if device A plays from 10:00-10:30 and then 10:15-10:45, the total time is 45 minutes, not 60. - + 1 more questions in this round (sign up to unlock)
System Design
4- 4
Type · API Design
Design a RESTful API for controlling basic functionalities of Nothing audio products (e.g., play/pause, volume control, EQ settings) that can be accessed by a companion mobile app. Consider authentication, error handling, and versioning. - 5
Type · Scalability
Imagine Nothing launches a new feature allowing users to share audio playback status (e.g., 'Listening to X on Nothing Ear (2)') to social media. Design a scalable system to handle potentially millions of users updating their status concurrently. Consider the backend infrastructure, data storage, and potential bottlenecks. - + 2 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · Algorithms
Given a list of user preferences for audio profiles (e.g., {'user1': ['bass-boost', 'noise-cancellation'], 'user2': ['bass-boost'], 'user3': ['noise-cancellation', 'spatial-audio']}), implement a function to find the most popular combination of preferences. If there's a tie, return any one of the most popular combinations. - 7
Type · Code Clarity & Design
Refactor the following Python code snippet (which simulates a simplified audio device state machine) to improve its readability, maintainability, and extensibility. Consider using classes, enums, or other design patterns. [Provide a moderately complex, procedural code snippet with magic numbers and unclear state transitions]. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
12- 8
Type · Past Experience
Tell me about a time you had to influence a stakeholder (e.g., engineer, designer, executive) who had a different opinion or priority than yours. How did you approach it, and what was the outcome? - 9
Type · Adaptability
Tell me about a time when project requirements or priorities changed suddenly. How did you adapt, and what was the impact on your work? - + 10 more questions in this round (sign up to unlock)
