Atlassian's Interview Process (2026)

Blog / Atlassian's Interview Process (2026)

The Atlassian software engineer interview process is highly structured and fully virtual, typically running 3 to 6 weeks from application to offer. Most candidates move through a recruiter screen, a technical screen via Karat, and a multi-round virtual onsite covering coding, system design, and a values-based behavioral round.

Recruiter Screen: A 30-minute conversation covering your background, interest in Atlassian, and logistics like salary expectations and location. Recruiters will typically clarify the seniority level you are being considered for, referred to internally as a P-level.
Technical Screen (Karat): Usually conducted by a Karat interviewer rather than an Atlassian employee, this round often starts with a handful of rapid-fire technical questions on topics like networking or OS basics, followed by one or two coding problems. Atlassian generally offers a redo of this round if you are unhappy with your performance, which is a fairly unique policy.
Coding and Data Structures Round: A 60-minute live coding session focused on algorithmic problem-solving. Atlassian interviewers pay close attention to code quality, naming conventions, and whether you proactively test your own code, not just whether your solution runs.
Code Design and Craft Round: A 60-minute round built around a real-world coding task rather than a LeetCode-style problem. Backend candidates might design a popularity tracking system, while frontend candidates may be asked to build a functional UI component like a search bar with debouncing.
System Design Round: A 60-minute discussion on scalability and architectural trade-offs, often framed around Atlassian's own product domain. Past topics have included designing a notification service for Jira or a real-time collaborative editor similar to Confluence.
Values Interview: A 45 to 60 minute behavioral round conducted by an interviewer from a different department, specifically assessing alignment with Atlassian's five core values. Many candidates cite this as the most important round, as strong technical performance does not compensate for a poor result here.
Hiring Committee Review and Offer: After the onsite, feedback goes to an internal hiring committee before an offer is extended. If successful, this is followed by an offer and negotiation discussion.

To prepare effectively, focus your study plan across these key areas that reflect the different stages of Atlassian's interview:

Data Structures and Algorithms: Algorithmic problem-solving with an emphasis on code quality and testing.
Low-Level Design and Craft: Real-world coding tasks focused on object-oriented design, extensibility, and clean code.
System Design: Scalability, architecture, and trade-offs relevant to Atlassian's product ecosystem.
Behavioral and Values: Structured behavioral questions mapped directly to Atlassian's five core values.

1. Data Structures and AlgorithmsAtlassian's DSA rounds test both correctness and craftsmanship. Expect medium to hard difficulty problems, with a clear preference for candidates who write clean, well-named code and test their own solutions without being prompted.Commonly reported topics include trees and graphs, string manipulation, and hash maps. Specific questions that have appeared include Lowest Common Ancestor of a Binary Tree, Rank Teams by Votes, and implementing the base logic for a Snake Game. Brushing up on trees and graphs is a solid starting point.For breadth of practice, work through our top 100 DSA questions, which covers the most frequently tested problem types across technical interviews at companies like Atlassian.

2. Low-Level Design and CraftThe Craft round is one of the more distinctive parts of Atlassian's process. Instead of a pure algorithm problem, you are given a real-world design task and expected to produce clean, extensible, production-quality code within the session.Backend tasks often involve object-oriented design with concurrency considerations, such as building a system with increasePopularity and getMostPopular methods that handles tie-breakers correctly. Frontend tasks might involve building a working UI component like a debounced search bar using React, so frontend candidates should review React fundamentals if that is their stack.Practice thinking about edge cases, naming conventions, and code structure as much as the logic itself. Explore Low-Level Design practice to get comfortable with this style of problem before your interview.

3. System DesignAtlassian's system design round tends to be grounded in problems that mirror real features in their products. You might be asked to design a distributed rate limiter for Jira APIs, a notification system, or a real-time collaborative editing layer similar to Confluence.Focus on trade-offs, scalability bottlenecks, and how you would handle failure scenarios. Interviewers want to see structured thinking, not a memorized template, so practice explaining your reasoning out loud. Build your foundational knowledge with High-Level Design concepts and use our System Design practice tool to simulate the whiteboarding experience.Familiarity with system design core concepts like rate limiting, message queues, and caching will give you a strong base for the kinds of topics Atlassian tends to ask about.

4. Behavioral and ValuesAtlassian's Values round is not a standard culture fit interview. Each question is mapped to one of their five core values, including 'Open company, no bullshit,' 'Don't #@!% the customer,' and 'Be the change you seek.' Candidates who treat this as an afterthought are frequently rejected, even with strong technical scores.Prepare two to three specific stories for each value using the STAR principle to keep your answers focused and concrete. Interviewers in 2025 have noted a strong preference for answers that show humility and genuine customer empathy over polished but generic responses.Our Behavioral Interview Course walks you through how to structure and deliver compelling value-aligned stories. The Behavioral Playbook is also worth reviewing for additional frameworks and example answers.

ConclusionAtlassian rewards candidates who combine solid technical skills with clear values alignment and a production-ready mindset. Start your prep early, prioritize the Craft and Values rounds alongside your DSA work, and practice writing clean code from day one. Follow the Atlassian Interview Roadmap for a structured, stage-by-stage plan to get you ready.
