You mentioned tests — did you write tests at [company] and at your last job?

Yes, in my previous jobs I regularly wrote tests for frontend applications. I mainly used Jest and React Testing Library for unit and integration tests of components.

I wrote tests to verify:

• Individual React components (rendering, interactions).
• Business logic layer (functions, utilities).
• Asynchronous operations with API mocks.

This helped identify errors early and maintain stability during refactoring.
