I interviewed with Atlassian 4 months ago and went through the entire interviewing process. There was a total of 4 interviews although I was told there would be 5.
1. Recruiter screening (30 min): straight forward with light behavioral questions
2. Hiring manager interview (45 mins): Behavioral questions that was scripted. The hiring manager read questions from a script and each question had multiple parts to it. He did give me a heads up that it was a set of scripted questions and that he would be reading and taking notes. I appreciated that. This interview style isn't my favorite as it makes it difficult to follow along and build a connection with the hiring manager. The Q&A section was appreciated as it gave time to actually connect with the manager.
3. Values Interview (30 mins): This interview was behavioral as well and completely focused on soft skills, communication, and handling of tough situations.
4. Case study, presentation, and technical interview (90 mins): This was a panel interview with 2 people. I was given a case study a week in advance and had to provide a 35 mins presentation followed by a technical interview. The recruiter wasn't able to give me much information regarding what the technical interview entailed so it was difficult to prepare. When I asked she said she didn't have an example so I just prepared the best I could. The purpose of the case study itself was to solve a customer issue and provide a recommendation using the Atlassian suite of tools including a budget friendly option. The technical questions ended up being more behavioral and focused on how I would respond to customer questions and feedback which wasn't too difficult. The interviewers were very nice which made the interview less intimidating as presenting to strangers can be a bit nerve wrecking.
Overall I thought the interview process was difficult but fair. The most disappointing thing was that after I spent over 40+ hours researching, creating a solution, and preparing for the presentation and interview I got ghosted. Before the interview the recruiter told me that they would make a decision by the end of the week, then a week after the interview they told me the team would need another week to decide but that they wanted to connect with me that same day or the next. I sent them my availability and never heard from them since. So that's a bit disappointing. I understand the nature of interviewing and the current competitive market however, I do think that if a company requires a case study to interview, they should treat candidates better.
