Atlassian Software Engineer Interview Questions

I would separate event collection, processing, and reporting so the system can scale without becoming brittle. Then I would think about deduplication, ordering, and whether the results need to be updated in real time or in batches. A strong design starts with the user’s actual reporting needs.

I would compare the options using maintainability, correctness, and delivery impact instead of arguing from preference. Then I would look for the simplest solution that satisfies the real requirement. Good collaboration means finding a decision the team can support, not just winning the discussion.

I would decouple event creation from delivery so spikes do not overwhelm the system. Then I would add retries, delivery tracking, and user preference handling so the system remains reliable as volume grows. Good notification design is mostly about dependability and control.

I would usually start with a hash map to count occurrences, then decide whether I need sorting, a heap, or buckets depending on the size of the input and the output I want. The best answer is the one that avoids more work than necessary. I would also mention the space cost so the trade-off is complete.

I would think about time zones, language, formatting, and how different regions may expect the product to behave. Then I would make the data model and UI flexible enough to adapt without custom code for every locale. Good internationalization is built into the system rather than added at the end.
