Your Role in Open Source Projects
Describe your most meaningful contribution to an internal or external open-source project. What was the motivation and outcome?
Why Interviewers Ask This
Adobe values open collaboration and community-driven innovation, evident in their heavy reliance on tools like Git and contributions to the broader ecosystem. Interviewers ask this to verify your ability to work asynchronously with strangers, adhere to strict code review standards, and drive projects forward without direct management oversight. They are specifically evaluating your initiative, technical communication skills, and genuine passion for engineering excellence beyond paid deliverables.
How to Answer This Question
1. Select a specific project where you had tangible impact, prioritizing external open-source over internal tools if possible, as it demonstrates broader influence. 2. Structure your response using the STAR method: define the Problem (a bug or missing feature), describe the Task (your proposed solution), detail the Action (research, coding, engaging maintainers), and highlight the Result (merged PRs, adoption metrics). 3. Emphasize the 'soft' aspects of open source, such as navigating code reviews, writing documentation, and communicating clearly with maintainers who may be in different time zones. 4. Quantify your outcome by mentioning lines of code added, bugs fixed, or how many users benefited from your contribution. 5. Conclude by connecting this experience to Adobe's culture of creativity and collaboration, explaining how these skills will help you integrate into cross-functional teams at the company.
Key Points to Cover
- Demonstrating proactive ownership by solving problems outside mandatory job descriptions
- Showing ability to navigate asynchronous collaboration and code review processes
- Providing concrete metrics on the impact of the contribution
- Highlighting communication skills with external stakeholders
- Aligning personal initiative with Adobe's collaborative and innovative culture
Sample Answer
In my previous role, I noticed that our team struggled with a specific performance bottleneck in an open-source visualization library we used internally. The issue was a memory leak when rendering large datasets, which caused crashes during client demos. Although fixing it wasn't part of my official job description, I decided to investigate the root cause. I spent two weeks analyzing the source code, reproducing the issue locally, and drafting a fix that optimized the garbage collection logic.
I then opened a pull request on the GitHub repository. The process involved rigorous back-and-forth with the core maintainers via comments and Slack. I had to refactor my initial approach based on their feedback regarding backward compatibility, ensuring my changes didn't break existing workflows for other users. After three rounds of revisions, the PR was merged into the main branch.
The outcome was significant: the library's stability improved by 40%, eliminating the crash issues entirely. This fix was adopted by over 500 downstream projects within six months. Beyond the technical win, this experience honed my ability to communicate complex technical constraints clearly to a diverse group of contributors, a skill I know is vital for collaborating across Adobe's global product teams.
Common Mistakes to Avoid
- Focusing only on the code written while ignoring the crucial collaboration and review process
- Describing vague contributions like 'fixing typos' without showing technical depth or impact
- Claiming credit for a project where the candidate played a minor role rather than leading the effort
- Failing to explain the motivation behind contributing, making it seem like a random act rather than strategic problem-solving
