Atlassian Software Engineer interview questions

The process was very streamlined. I applied via their website and was immediately sent a link to Hacker rank, a one hour coding challenge. I did the challenge soon after and on the same day I was sent an email and offered an interview. The first interview I had was over skype with the recruiters, which was just a few standard HR questions like "why do you want this role at Atlassian", "tell us a bit about yourself", etc. The next stage was a set of three back to back interviews, each about an hour long: * A whiteboard/design interview where I was asked about a system I had previously worked on. * A technical interview where I was asked about my computer science and technical knowledge. * A coding interview where I was asked to implement a simple data structure in Java, with tests and benchmarks supplied. Later that week they followed up on the interview and the next week I received the offer; I was given a week to accept. Overall I was very happy with the process, especially with how prompt they were relative to other comparable firms. I was also happy that in each interview I had the opportunity to ask my interviewers about their experience with the company.

It starts off with a phone screen at the beginning and then an online test which is relatively easy and deals with algorithmic style questions (You only need to answer 2 of the questions). Then there's an onsite interview that is "Coding", "Technical" and "Whiteboard". The coding interview is just a simple stack question. The Technical interview is all about random questions about the implementation of data structures and what 'classes' or 'interfaces' are. The whiteboard interview is you sitting there talking and using a whiteboard to describe a project that you have worked on. My experience was pretty negative because the Coding interviewers said that my answer was wrong in the feedback even though during the interview they said "Yeah it looks like you've got it" which was very strange. The technical interviewers seemed to really not enjoy that I was describing interfaces from a software architecture standpoint and not from a layman's standpoint so there was a bit of a communication failure there. But they labeled that as having "a technical knowledge gap" which is a very weird criticism as I have demonstrable experience with java in the form of building Android games using all sorts of data structures and fast algorithms while making it architecturally sound. The Whiteboard interview was by far the worst. The two interviewers were clearly checked out of the entire process. I was describing very technical distributed computing project and was trying to make sure that they were following along and asked them to stop me at anytime they felt that I was being unclear. Their feedback was that my project was not "technical" enough because I had no UI or customer facing requirements which is absolutely asinine. Mind you, they didn't specify what they were looking for during the whiteboard interview. My advice to Atlassian would be to make sure that their interviewers are actually engaged in the interviews and that they at least put in some effort in their criticism instead of giving completely insane feedback (especially that my project was not 'technical enough' because it had no UI!)
