I was contacted via LinkedIn by an internal recruiter. All interviews were done via Zoom due to COVID-19. Interviews are code agnostic, so you can use whichever language you want.

There were a total of 5 interview stages:

1. Coding design Gauges your coding design ability. Will ask you to implement a feature (I got rate limiting) to see your general OOP/code design chops.
2. Data structures Will start by specifying an easy problem that gets progressively harder as they add more requirements for the problem.
3. System designs You'll be tasked with designing a subsystem. Pretty straightforward -- make sure to ask clarifying questions and don't presume.
4. Team interview Interview with potential team lead/manager. Normal stuff; asks about your previous experience with tech, your development process, etc.
5. Values interview They'll go through the Atlassian values one by one and ask questions revolving around each. I recommend reading up the values and noting down some stories about each one.

My interview process took a bit longer than usual at around 1 month. I cleared all the stages in about 4 weeks, but had to wait because there was another potential team with more urgent hiring need so I waited to had a chat with the team lead.

All in all, it was the best interview process I have gone through. All the interviewers were very personable -- there were no gotcha esoteric questions and it felt more like talking to peers. Every question asked was relevant to the job. The recruiters and candidate experience manager were extremely professional and very prompt in following up. You also get feedback after every interview (and a summary in the end) which were very on-point and very much appreciated.

Scenario for each values.
