Atlassian Principal Software Engineer interview questions

Had a great interview experience at Atlassian. The HR of company are friendly and responsive, interviewers are knowledgeable and positive during interview. I had a total of 6 rounds of interview 1. HR - HR just asks about your experience and check skills based fitment. 2. System Design - Question - Design a Url Scarping System. I was able to solve this. However the expectation is go deep and design the core Scrapping API. Which I was able to do after the interviewer insisted. So be ready to show case your API design skills, URL, Request, Response, Data Model etc. Also be ready to provide the tech stack along with tradeoffs. 3. Leadership and Craft - Lot of questions around delivery, project management, stakeholder management, mentoring etc. I did pretty well in this. 4. Values - This is about atlassian values, HR will tell you how to prepare for this. I did pretty well. 5. Data Structure - Last Hero Problem. In an F1 race find the person who has done fastest lap in all of race. I solved it using HashMap of racer and max lap time. Later on I sorted the map and gave the last lap hero. I made a silly mistake and my test cases were failing. Hence I did not make it. 5. LLD - I dont remember the question. It was around Most Popular content. I used HashMap for storing content and frequency (thumbs up/thumbs Down)

Coding task, algorithms. It was not very difficult, all worked. But probably was not as good as it should be. Interviewer was polite and professional, task was described, we had a chat about solution steps.
