HR Screening and Karat Interview.
I don't think they are hiring for the level advertised. They are gauging your level based on how you perform in the interviews. I fished this information during the HR screening.
I like Atlassian. The only problem I have with their process is the Karat round. You have 20 minutes of system design questions and 30 minutes of coding. There are 10 minutes for intro and explanation.
The problem I see with this is the 30-minute coding interview. When the interviewer takes anywhere from 7-10 minutes describing the problem and test cases, 20 minutes isn't sufficient to humanely solve something when provided with a next-to-shite coding environment. Let's accept, nobody is going to code in that environment without looking up libraries or having a syntax error while compiling and running it. It is very hard to gauge someone in that kind of intimidating environment.
So, my advice is: they won't recruit you as a Principal. This round is a way to level you down from a Principal to a Senior or even lower.
By the way, beware, the guys from Karat boast that they have taken 1500/2500 interviews before they get into the round, which I felt was a bit funny.
