Practice questions in Atlassian's style

Original ZorixOS questions written the way Atlassian interviews, so you rehearse the real format. Not claimed as asked at Atlassian.

  1. You're tasked with improving the performance of Jira's issue creation workflow. Describe how you would approach diagnosing the bottlenecks, considering that millions of issues are created daily across diverse customer instances. What tools and metrics would you use?

    Software EngineerPerformance DebuggingTests: Evaluates the candidate's ability to debug complex, high-scale systems and identify performance issues.

  2. Atlassian's Confluence is used for knowledge sharing. Imagine a scenario where a large enterprise customer reports that their Confluence site is experiencing intermittent slowness and search functionality is unreliable. How would you investigate this, focusing on potential issues within Confluence's architecture and integration points?

    Software EngineerSystem Design DebuggingTests: Tests understanding of distributed systems, debugging strategies in a SaaS environment, and problem decomposition.

  3. We are introducing a new collaborative editing feature in Jira for project descriptions. Design the system architecture for this feature. Consider real-time updates, conflict resolution, and scalability for thousands of concurrent users across many projects.

    Software EngineerSystem DesignTests: Assesses system design skills, understanding of concurrency, and distributed system principles.

  4. A customer is experiencing data corruption in their Bitbucket repository, leading to lost commits. Describe your debugging process to pinpoint the root cause, considering potential issues with the Git implementation, network stability, or underlying storage mechanisms.

    Software EngineerDebuggingTests: Evaluates debugging skills in a critical code hosting scenario, including understanding of Git internals and data integrity.

  5. Jira Software has a vast ecosystem of apps. If a third-party app is causing unexpected behavior or performance degradation in Jira Cloud, what steps would you take to diagnose the issue? How would you balance assisting the customer with troubleshooting the app versus identifying if the issue is within Jira itself?

    Software EngineerTroubleshooting Integration IssuesTests: Tests ability to debug issues involving external integrations and manage customer expectations in a complex ecosystem.

  6. You're designing a new feature for Trello that allows for more dynamic project planning. How would you define the core metrics to track the success of this feature? Consider adoption, engagement, and impact on user productivity.

    Software EngineerMetrics DefinitionTests: Checks understanding of how to define measurable success for software features.
