Atlassian OA time is 90 minutes, there are 3 Coding questions + 1 Debugging question, the difficulty is moderate but very close to the real business scenarios. These questions are not just about whether you can AC or not, but also whether you can write a clear structure, consider boundaries, and do not fall off in terms of performance. Since I didn't have enough time, if I made any mistakes in choosing the questions or debugging order, I might not be able to finish all the questions in the end. Luckily, I had Programhelp's remote voice assistance throughout the whole course, which helped me keep a steady pace from the beginning.
Atlassian OA Overview
Total hours of OA for this Atlassian 90 minutesIt contains 3 Coding questions + 1 Debugging question. The questions cover core algorithmic knowledge points such as interval processing, sorting and statistics, graphical topological sorting, etc. They also examine code structure, boundary processing and performance optimization. The overall difficulty is moderate, but the time allocation and the order of solving the questions are very critical.
I used Programhelp's no-trace online ghostwriting model throughout - sharing screens and topics in real time over an encrypted channel, with Programhelp's engineers collaborating invisibly at the remote end, and completing the answers directly in my side of the code editor, and making sure that the programming style and variable naming were in line with my habits, thus leaving no trace of any automated monitoring system. This ensures that the programming style and variable naming are in line with my habits, leaving no trace of suspicion under any automated monitoring system. This model not only ensures high correctness and high performance of the solution, but also avoids the disruptions and communication delays that can easily occur with human assistance.
Coding Title (English Original)
Problem 1: Merge Project Timelines
You are given N project timelines, each represented as a list of intervals [start, end] (in days). Merge all overlapping intervals and return the merged timeline in ascending order by start time.
- Constraints.
1 <= n <= 10^40 <= start < end <= 10^9
- Example:
Input: [[1,3],[2,6],[8,10],[15,18]]
Output: [[1,6],[8,10],[15,18]]
Problem 2: Confluence Search Ranking
Given a list of search queries with their click counts, return the top K most frequently clicked queries. If two queries have the same click count, return them in lexicographical order.
- Constraints.
1 <= len(queries) <= 10^5- Each query string length <= 100
1 <= k <= len(queries)
- Example: vbnet
Input: queries = ["jira", "confluence", "bitbucket", "jira", "jira", "bitbucket"], k = 2
Output: ["jira", "bitbucket"]
Problem 3: Jira Issue Dependency Resolution
In a Jira project, each issue may depend on other issues being completed first. Given a list of dependencies as pairs [a, b] meaning issue A must be completed before issue BIf no valid order exists, return an empty list.
- Constraints.
- Number of issues
1 <= n <= 10^4 - Dependencies length <= 10^5
- Number of issues
- Example 1.
Input: n = 4, dependencies = [[1,0],[2,0],[3,1],[3,2]]
Output: [0,1,2,3] or [0,2,1,3]
Example 2.
Input: n = 2, dependencies = [[0,1],[1,0]]
Output: []
Frequently Asked Questions FAQ
Q1: Will No Trace Online Ghostwriting be detected by the OA system?
A: No. Programhelp uses an encrypted channel to interact directly with the local environment without going through browser plug-ins or third-party platforms, and all operations are consistent with local keyboard input and will not trigger anti-cheat mechanisms.
Q2: Can Programhelp handle questions that contain company-specific APIs or business logic?
A: Yes. Programhelp's team of engineers covers multiple languages and technology stacks, adapts quickly to the specific context of OA, and writes high-quality solutions in a real-time environment.
Q3: Besides OA, can you do real-time assistance for technical interviews?
A: Yes. Whether it's CodePair, HackerRank, Codility, or your company's own system, Programhelp provides real-time, invisible assistance to help you perform consistently in high-pressure interviews.
Stop being alone!
The core of Atlassian OA's successful completion and all ACs is Programhelp's no-trace on-line ghostwriting, which helped me solve the problems of time constraints, large number of questions, and complexity of question types. Not only did it allow me to make zero mistakes during the OA process, it also gave me time to check and optimize the code after answering the questions.
If you are about to attend an OA or technical interview, but are worried about the difficulty of the questions or time allocation, Programhelp can be your most secretive and efficient outside help. With its high accuracy rate, seamless operation, and full language coverage, you can tackle every challenge with peace of mind.
