The first stage of the interview process was to complete a series of programming challenges on HackerRank over 90 minutes. 5 questions were given, however you only had to complete a minimum of 2 to progress to the next stage. After this there was a short 30 minute phone interview, to gauge your interest in Atlassian and level of technical experience. Finally there was a 3 hour face-to-face interview broken up into 3 different sections. The first section was a technical interview, used for the interviewer to understand the breadth of your knowledge in software development. A range of questions were asked ranging from the security of web applications to object oriented design principles. The second section asked you to explain a project that you'd worked on in detail, where you had to describe and reflect on the different decisions that you made completing it. The final stage was a Java coding test, where you had to implement a class while explaining your thought process to the interviewer. The process was very smooth, and HR did a great job communicating with me in an understanding and timely manner. I ended up declining the (very generous) offer as I had a competing one that suited me better at the time. Would definitely recommend applying to Atlassian however, they were very hard to turn down!
