Scenario-Based Questions

Definition

Interview questions that present a complex, real-world business problem and ask you to design the Next.js architecture to solve it.

Explain Like I'm New

There is no 'right' answer. The interviewer wants to hear your thought process. They want to see if you can balance performance, development speed, and cost.

Real World Example

Scenario: 'We are building a massive e-commerce site with 1 million products. Prices change every 5 minutes. SEO is critical. How do you architect this in Next.js?'

Question

Stock data dashboard?

Answer

Since it polls every 2 seconds and SEO doesn't matter for a private dashboard, I would completely avoid Next.js Server Components for this piece. I would use a Client Component with a library like TanStack Query (React Query) to handle the aggressive client-side polling and caching.

Question

Migrating legacy SPA?

Answer

No. I would use the Incremental Adoption strategy. I would set up Next.js `rewrites` in `next.config.js`. I would build the new Homepage in Next.js, and configure the router to proxy all other traffic back to the old legacy server. Then, I migrate one page at a time.
