How to Pass the Linear Software Engineer Interview in 2026

The Linear DNA (TL;DR)

Linear values craftsmanship, clear communication, and a strong product sense. They grade for candidates who can build elegant, performant solutions, integrate seamlessly into a design-driven culture, and demonstrate a bias for action and impact, often through rapid iteration and user-centric thinking.

The Linear 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 Linear interview outcomes, avoid these common traps:

Giving a generic answer about wanting to work at a fast-growing startup.
Not handling IDs that are shorter than 3 characters.
Incorrectly identifying the prefix boundary.
Describing a superficial fix like updating a dependency version

Test Yourself: Real Linear Questions

Three real prompts pulled from our database.

Type · Algorithmic

Implement a function that takes a list of Linear issue IDs (strings) and returns a map where keys are the first 3 characters of the ID and values are lists of issue IDs starting with those characters. For example, 'LNR-123' and 'LNR-456' should be grouped under 'LNR'.

Type · Code Clarity

Refactor the following pseudo-code snippet for fetching and processing user data to be more modular, readable, and testable. Explain your design choices.

Type · System Design

How would you design a system to detect and flag duplicate issues reported by users in Linear? Consider the challenges of defining 'duplicate' and the scale of data.

9 of 15 questions shown

Recruiter Screen

1
Type · Motivation
Why are you interested in Linear, and what specifically about our mission or product excites you as a software engineer?

Coding Screen

2
Type · Algorithmic
Given a list of user feedback items, each with a timestamp and a text body, write a function to group feedback into daily summaries. Each summary should contain the count of feedback items for that day and a list of unique keywords (e.g., 'bug', 'feature request', 'UI issue') found in the feedback. Assume a simple keyword extraction logic.
3
Type · Algorithmic
Implement a function that takes a list of Linear issue IDs (strings) and returns a map where keys are the first 3 characters of the ID and values are lists of issue IDs starting with those characters. For example, 'LNR-123' and 'LNR-456' should be grouped under 'LNR'.

System Design

4
Type · System Design
Design a system to suggest relevant Linear issues to a user based on their current activity (e.g., issues they are viewing, commenting on, or assigned to). Consider scalability and real-time updates.
5
Type · System Design
Design a notification system for Linear that can handle sending timely updates to users about issue changes, mentions, and assignments. Consider different notification channels (in-app, email, Slack).

Onsite Coding

6
Type · Debugging
A user reports that sometimes, when they type quickly in Linear, their keystrokes are dropped or appear out of order. Analyze this potential issue and propose a debugging strategy. You can assume a typical web application architecture (frontend, backend, WebSocket).
7
Type · Algorithmic
Implement a function to efficiently find the longest common prefix among a list of Linear project names. For example, given ['linear-app', 'linear-api', 'linear-docs'], the longest common prefix is 'linear-'.

Behavioral / Leadership

8
Type · Ownership
At Linear, we often obsess over the feel of the UI, such as the latency of an issue status transition or the snappiness of the command menu. Tell me about a time you noticed a subtle performance or UX friction point in a product you were working on that others had accepted as normal. What specific steps did you take to investigate the root cause, and how did you advocate for the polish required to fix it?
9
Type · Collaboration
Describe a challenging technical disagreement you had with a colleague or team member while working on a Linear feature. How did you approach the situation, and what was the resolution?
