Never waste time interviewing with Atlassian. I went through 5 rounds of interviews: 1. Phone screening: Self-introduction and discussion of past projects. 2. Karat: Basic HTML, CSS, and JS questions, which I passed. 3. JS coding interview: Simple JS questions, which I passed. 4. Browser coding interview: Coded a simple UI, which I passed. 5. System design: The topic was a very popular question. I had reviewed it twice on YouTube following two popular videos, but ultimately, I did not pass. In the end, HR told me I didn't pass the system design interview and that there were no suitable positions available at the moment either. I strongly suspect that my failure in the system design interview was because Atlassian actually had no new positions open; they just wanted to keep HR looking busy. It's impossible that I failed the system design interview since I had prepared exactly for this question using very popular YouTube system design tutorials. My final advice: If you insist on interviewing with Atlassian, make sure to confirm with HR that there are open positions. Otherwise, they might just find any excuse to fail your interview.
