An utter waste of time!! All the negative experience reviews are correct, word-for-word.

I applied for Principal AI/ML Engineer. I must say I studied really hard for the stage 1 of the interviews:

• LLD Coding
• MLSE Craft Interview

The LLD Coding interviewer is some stupid tier-3 graduate with absolute hate for tier-1 grads. Despite completing a working, end-to-end solution, I was told I didn't write test cases (I had explicitly asked that chap if I needed to write test cases, even using a TDD approach).

The MLSE Interview involved a discussion about my project. The interviewer, as per his feedback, was also in shock and awe of my concept clarity. He then asked an ML system design question. I answered it very well, which he again praised. However, I missed error metrics/model assessment stages, which he could have just prompted me to answer.

But no! Because they only want to "reject" candidates. The interviews are happening very, very nominally. They'd be only doing internal promotions for upward mobility and never really hiring an outsider for Principal roles.

Stop wasting your time preparing for Atlassian! I, along with more than two dozen interview feedbacks on Glassdoor, totally mean it!

Trivial LLD problem: the solution is what that chap came prepared with.

Project and Sys Design: Explain your project so well that they at least consider you moving forward! You will never be able to impress them despite a working solution and a holistic high-level system design.
