Structure your answer as a concise narrative that highlights your TypeScript journey, emphasizing depth of experience and specific technical challenges you've solved. Focus on trade-offs you've made when using TypeScript, such as strictness settings, migration strategies, or performance considerations, to demonstrate engineering maturity.
Pro tip: Quantify your impact where possible (e.g., 'reduced runtime errors by 30% after adopting strict mode') and mention how you've influenced team practices, like setting up linting rules or contributing to shared type definitions.
State how long you've used TypeScript and in what contexts (e.g., frontend, backend, full-stack) to set the stage.
Choose one or two impactful examples where TypeScript played a key role, such as migrating a large codebase or designing complex types.
Explain decisions you made regarding TypeScript configuration, type safety vs. development speed, or integration with other tools.
Describe what you've learned about TypeScript's strengths and limitations, and how you apply best practices in your work.
Relate your TypeScript experience to Meta's engineering culture and the specific challenges of the role, showing enthusiasm for contributing.
