I'm sharing my detailed Atlassian interview experience for SWE-II P40 backend role. I'll share the questions if I remember for those rounds, but most of the questions were from interview experiences I found on leetcode. Before I start, please avoid asking these unnecessary informations 1. My current company 2. My current compensation 3. Offered compensation ( as it is not discussed yet ) So, I reached out to multiple recruiters through mail or linkedin message requests, on which one of the recruiter replied after 20 days and scheduled screening round. Overall from the day recruiter reached out till today almost 2 months are
passed, and today I called recruiter and got to know that HC has approved my profile and will assign another recruiter that will drive team matching process.
**
Round 1 Karat Screening Round (1 Hour)** It was an hour long round which was mostly divided into two parts. First part was 20 mins rapid fire round where he asked some system design scenarios and I've to suggest possible solutions with justification. And second part was having 2 DSA questions mostly easy-medium difficulty level. After 3 days recruiter informed that screening was cleared and started main Atlassian interview rounds
**
Round 2 LLD (1 Hour)** It was an LLD round and similar question that mentioned as here. Overall round was medium and interviewer was friendly and communicating properly.
**
Round 3 DSA (1 Hour)** I was asked question similar to merge interval problem just with different wording and few follow ups that required sweep line approaches. Overall round was easy for me as I've huge practise in DSA and interviewer was friendly and communicating properly. 4 days after these two rounds, I called recruiter and was informed that feedback was positive and can move to system design round.
**
Round 4 System Design (1 Hour)** It was a Top-k heavy hitter problems for confluence page with a variation that user should no be shown the pages in top k which he has already viewed. You can search Top-k heavy hitter on internet you'll find lots of variation of it. Overall round was good, few small mistakes I did but recruiter was supportive and he fully focused the interview on areas what he needs to see and clarify assumptions beforehand so that I don't waste time on those. 1 hour after the interview, recruiter informed about positive feedback and can move to MV rounds
Round 5 & 6: Management and Values (1 hour each) Both of the rounds were similar. I was asked some situations and based on my previous work experience I've to justify those situations basically in STAR format. Only difference is that questions in values round were more aligned toward Atlassian values. After 3 days, I was informed that both rounds were also positive and waiting for HC approval. Since it was a year end time so it took almost a month. Final Verdicts:
LLD Hire, High Confidence DSA - Hire, High Confidence
HLD Hire, Medium Confidence Management - Hire Values - Hire Will update once team matching will progress.
Hope for the best!!!

About Atlassian Interview Reports
This question was reported by a candidate who interviewed at Atlassian. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Atlassian are the higher-signal extractions to take from this report.
For broader preparation context, the Atlassian interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Atlassian reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Atlassian Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Atlassian reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
