Atlassian Interview Guide
10% easy, 75% medium, 15% hard · 15 problem suggestions · Hash Maps, Priority Queues, Design
Overview
Atlassian interviews use Karat for the initial screen — a third-party interviewer conducts the coding round, which means a more standardized experience than most companies. The onsite focuses on clean code, trade-offs, and values alignment. With 75% medium problems, the difficulty is consistent and predictable. Atlassian wants engineers who write maintainable code and think about collaboration — fitting for a company that builds Jira, Confluence, and Trello. The values interview carries real weight. Atlassian's culture emphasizes 'Don't f*** the customer,' 'Play as a team,' and 'Be the change you seek.'
