How do I answer 'What would you do differently with more time?' in a machine coding follow-up?
Be honest. Mention features you would add, CSS you would polish, edge cases you would handle, or tests you would write. This shows self-awareness and a desire for quality, which interviewers appreciate.

More FAQs in Machine Coding Round: Follow-Up Questions to Expect
How would you scale for 10,000 items (virtualization)? How would you optimize performance (debounce, memo)? How would you make it accessible (ARIA)? How would you test it? Why did you structure the code this way? What would you do differently with more time?
Discuss virtualization (render only visible items with react-window or react-virtualized), pagination, lazy loading, and efficient data structures. Explain that rendering 10,000 DOM nodes is slow, and virtualization solves it by rendering only the visible ones.
Discuss ARIA roles, keyboard navigation (tab, arrow keys, enter, escape), screen reader support, focus management, and semantic HTML. Explain that accessibility is not optional and benefits all users.
