How do you handle versioning and breaking changes in a shared library?

WHAT THIS TESTS: This question evaluates whether you can govern a shared design system across design and engineering boundaries. The interviewer wants to know if you understand that a Figma library is a production dependency for multiple teams, not just a design artifact. They are looking for process thinking around release management, communication hygiene, and cross-functional alignment.

A GOOD ANSWER COVERS: A strong response hits four areas in order. First, adopt Semantic Versioning for the design library, using major bumps for breaking changes like renamed tokens or removed variants, minor bumps for additive changes, and patch bumps for fixes. Second, establish a protected main file and use Figma branching so designers iterate in isolation; merges happen only after review and scheduling. Third, publish a visible changelog and give consuming teams advance notice before releases, especially around their code freezes and release trains. Fourth, keep design tokens and component naming in sync with the codebase so version numbers in Figma map to package versions in code.

COMMON WRONG ANSWERS: A red flag is treating Figma Publish as if it were Git version control. Another weak pattern is saying you would just message the team in Slack after publishing, with no changelog or versioning. Saying breaking changes are fine because teams can simply detach instances also signals a lack of operational discipline. Finally, suggesting separate library files per team avoids the question; the interviewer wants a shared source of truth.

LIKELY FOLLOW-UPS: The interviewer may ask how you handle urgent hotfixes when multiple apps are on different versions. They might also ask how you deprecate a component without breaking existing screens, or how you enforce the branching policy when designers are used to working directly in the main file. Another common pivot is asking how you measure adoption or rollback a published change.

ONE CONCRETE EXAMPLE: Suppose you need to update a button component to meet new accessibility contrast requirements, which changes the default color token. You create a Figma branch named button-a11y-contrast, update the token, and open a review. You schedule the change for version 2.0.0 because it alters the default appearance. Two weeks before the release, you post a changelog entry and notify all consuming teams with the new version number and migration steps. You align with engineering so the code token release matches the Figma library version. After teams confirm they are ready, you merge the branch into main and publish.
