Describe a workflow to sync Figma tokens to front-end code

WHAT THIS TESTS: This question probes whether you understand design tokens as infrastructure rather than documentation. The interviewer wants to see if you know how to close the loop between design and engineering using version control and automated transformation pipelines. Senior candidates should demonstrate that the token file itself is the contract, not a secondary export.

A GOOD ANSWER COVERS: First, the workflow starts in Figma with Tokens Studio where designers manage tokens in sets and themes. Second, the plugin pushes or syncs token data to remote storage, ideally a Git repository, producing a W3C DTCG compliant JSON file. Third, developers treat that JSON as the single source of truth; it lives alongside application code and triggers CI on change. Fourth, a transformation step, typically using Style Dictionary or SD Transforms, reads the JSON and generates platform-specific artifacts like CSS custom properties, Sass variables, or JavaScript modules. Fifth, the generated files are imported by the front-end codebase, and the pipeline prevents drift because any design change must pass through the same review and build process as feature code.

COMMON WRONG ANSWERS: Saying the key artifact is a Figma file or a PDF style guide misses the point entirely. Claiming developers should manually copy hex codes from Figma indicates a broken workflow. Identifying generated CSS as the key artifact is also wrong; CSS is an output, but the canonical artifact is the JSON token file that enables cross-platform reuse. Another red flag is omitting Git sync or version control, which means there is no auditable source of truth or rollback capability.

LIKELY FOLLOW-UPS: How would you handle token references and aliases so that a semantic token like primary-action maps to a primitive color? How do you manage themes, such as dark mode, across the same JSON structure? What happens when a designer renames a token that is already referenced in production code? How would you validate tokens in CI to catch broken references before they reach the codebase?

ONE CONCRETE EXAMPLE: Imagine a team using Tokens Studio with the GitHub sync provider. A designer updates the border-radius-sm token from 4px to 8px and pushes the change to the design-tokens repo. The pull request triggers a GitHub Action that runs Style Dictionary, which transforms tokens.json into variables.css and tokens.js. The front-end app imports variables.css, so after the PR merges and the app rebuilds, every component using border-radius-sm updates automatically without a developer manually editing a stylesheet.
