Atlassian Software Engineer Interview Questions

I would keep the code readable, small enough to understand quickly, and covered by tests that reflect real behavior. Then I would use names and structure that make intent obvious instead of clever but confusing shortcuts. Maintainable code saves time every time the team comes back to it.

I would model the routes in a trie so lookups are fast and route matching stays organized. Then I would define how wildcards are resolved so the behavior is predictable and easy to debug. A strong answer balances flexibility with clear matching rules.

I would first understand what actually changed and whether the new requirement affects the core architecture or just the implementation. Then I would adjust the plan in a way that protects the schedule and keeps the design clean. Good engineers adapt without losing sight of quality.

I would parse the input, extract the fields I need, aggregate them into useful summaries, and sort the output in the expected order. Then I would make sure the solution handles edge cases such as missing data or malformed lines. The main goal is to produce correct results in a clear and reliable way.

I would focus on tests that protect important behavior without making the codebase slow to change. That usually means a mix of unit tests, integration tests, and a few end-to-end checks for critical flows. The best test strategy gives confidence without turning every change into a burden.
