# Full-Stack Engineer interview at Atlassian: questions, process & how to prepare

How to prepare for the Atlassian Full-Stack Engineer interview in 2026 — the real process, what they screen for, sample questions, and a free AI mock to practice out loud.

**Quick answer:** The Atlassian Full-Stack Engineer interview runs 4 main rounds: coding, system design, frontend + backend deep-dive, and behavioral. Study Atlassian's five values ('Open company, no bullshit', 'Don't #@!% the customer') and have stories that demonstrate them — the values round can sink an otherwise strong loop. Write clean, well-reasoned code and narrate your thinking. Practice each round out loud before the real thing.
