I went through Atlassian’s coding design interview recently, and the experience was surprisingly poor for a company of this scale. The exercise itself was simple, and I completed the implementation correctly. The interviewer gave me positive feedback on the spot, saying the solution looked good and that I solved everything they asked, including the scale-up question.

But the final result from Atlassian was the opposite: a rejection with no explanation whatsoever. When I specifically requested feedback, especially since what I was told live contradicted the official outcome, I received no response or clarification.

Recruiter communication throughout the process was equally disappointing, often taking 2-3 business days to reply to straightforward questions, which added to the overall sense of disorganization.

The exercise itself was simple: implement a small rating system where each agent receives 1-5 ratings, maintain a running average, and return agents sorted by their average rating and number of ratings.
