Atlassian·Machine Learning Engineer·Onsite - System Design / Architecture

Jul 2026
System design round at Atlassian for an ML Engineer role, basically one big question about building an internal enterprise chatbot that integrates with Confluence, Jira, and similar tools. Heavy on architecture and production concerns, less about ML theory than I expected.
  • Design an internal enterprise chatbot that lets employees ask questions in natural language, pulling answers from internal tools like Confluence and Jira, while enforcing access control, supporting both document Q&A and action-based workflows, and keeping everything auditable. Walk through the high-level architecture, key components, and how you'd evaluate and monitor it in production.

“This is a beast of a question and I think I underestimated how many distinct sub-problems are packed into it.”

Atlassian·Machine Learning Engineer·Onsite - Behavioral / Leadership

Jul 2026
Behavioral round for an ML Engineer role at Atlassian, focused entirely on values alignment and leadership signals. Standard stuff but the follow-up probing caught me off guard a few times.
  • Tell me about a time you pushed back on a decision or requirement you disagreed with.
  • Describe a situation where you drove a meaningful change or improvement in your team or process.
  • Can you give an example of helping someone else grow, through coaching or mentoring?
  • Walk me through a time you had to make progress on something without clear direction or requirements.
  • Tell me about a mistake you made and how you handled it.

“I had a decent story ready but the follow-up on how I handled the conflict after pushing back is where I fumbled.”

Atlassian·Data Scientist·Technical Phone Screen

Jul 2026
SQL question for a Data Scientist role at Atlassian. One question, reasonably tricky, the kind where you think you've got it and then realize there's a wrinkle you almost missed.
  • Given a team table and a game table, write a single SQL query to find the team name of the 2023 championship winner. The winner could be stored as either team_id or opponent_team_id, there are no ties assumed, but if one exists in the data you should break it by higher score. No hard-coded IDs allowed.

“The part that almost got me was the bidirectional storage.”

Atlassian·Software Engineer·Onsite - Multi Round

Jul 2026
Got an SDE intern offer from Atlassian for summer 2027 after three rounds: a tough OA, an AI-assisted coding session inside a live repo, and a values-based behavioral round with a senior engineer. The OA was the hardest part by far; the rest was more manageable than expected.
  • You're given access to an unfamiliar codebase in an IDE with an AI coding agent. Debug existing issues and implement new features using the agent.
  • Describe a situation where you demonstrated one of our company values.

“This was way less scary than it sounds.”
