Atlassian Principal Software Engineer interview questions

AN UTTER WASTE OF TIME!! ALL THE -VE EXPERIENCE REVIEWS ARE CORRECT WORD-FOR-WORD. I applied for Principal AI/ML Engineer. I must say I studied really hard, for the stage1 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, and despite completing a working END-TO-END Solution, I am told that I didnt write test cases(I had explicitly asked that chap if I need to write test cases, even a TDD approach). The MLSE Interview has a discussion about my project- he as per his feedback is also in shock-and-awe of my concept clarity, and then he asks an ML System Design question, I answer it very well which he again praises of, but I missed on error metrics/model assessment etc. stages which he could have just prompted me to answer around? But no! because they only want to "reject" the candidates- The interviews are happing very very namesake!! they'd be only doing internal promotions to upward mobilities and never really hire an outsider for Principal roles. STOP WASTING YOUR TIME PREPARING FOR ATLASSIAN! I, alongwith more than 2 dozen interview feedbacks on Glassdoor, totally mean it!
