Roll out a breaking change to a core public API
This tests risk management while evolving a public API contract. A strong answer covers versioning, phased deprecation with SLAs, migration tooling, and proactive communication. Red flag: proposing a hard cutover without sunset or migration support.
This evaluates your ability to balance technical delivery with ecosystem stewardship when altering a public API contract. A great response details a versioning approach such as URL or header negotiation; a deprecation policy with explicit timelines and sunset dates; tooling like breaking-change detectors and migration guides; plus communication through changelogs and developer portals. Red flag: Recommending a sudden hard cutover that ignores migration cost and offers no backward-compatibility bridge.
