Iterative Development and Debugging Questions

Assess methodical engineering practices for delivering reliable software. Topics include clarifying requirements, designing small and safe changes, writing unit and integration tests, using instrumentation and logging, reproducing and isolating bugs, performing root cause analysis, and iterating with rapid feedback loops. Candidates should demonstrate techniques for narrowing faults such as binary search of changes, isolating components, adding assertions and telemetry, and verifying fixes with automated tests to avoid regressions.
