Q1: What is the primary purpose of the `useEffect` hook in React?

To perform side effects in function components, such as data fetching, subscriptions, or manually changing the DOM.

Q2: You mentioned improving page load times by 40%. Can you describe two specific techniques you used to achieve this?

I implemented code splitting using dynamic imports to reduce the initial JavaScript bundle size. Additionally, I optimized all our image assets by serving them in modern formats like WebP and implementing lazy loading.

Q3: How would you approach building a highly accessible and reusable modal component for a design system?

I would use a React portal to render the modal at the top of the DOM tree to avoid z-index issues. For accessibility, I would implement focus trapping, handle the Escape key for closing, and use appropriate ARIA roles like 'dialog' and 'aria-modal'.

Q4: Describe a situation where you had to mentor a junior engineer. What was your approach?

A junior engineer was struggling with state management. I paired with them to refactor a component from using complex local state to using a shared context, explaining the benefits of centralized logic. I focused on guiding them to the solution rather than just giving them the answer.
