I applied through an employee referral. The process took 4 weeks.
Questions asked were around LLD on rate limiters, DS algo questions were easy to medium, and system design was difficult as it was very ambiguous and had too many dots to connect.
The following metrics were computed from 3 interview experiences for the Atlassian SDE-2 role.
Atlassian's interview process for their SDE-2 roles is fairly selective, failing a large portion of engineers who go through it.
Candidates reported having very good feelings for Atlassian's SDE-2 interview process.
