Interviewer Expectations for this Question

Core Competency
Assesses fundamental understanding of Next.js conventions, runtime behavior, and memory/performance considerations.
02
Evaluation Criteria
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
Comprehensive Model Answer
Verified Solution
In the Next.js Pages Router, AMP was enabled on a per-page basis by exporting an amp configuration object:
### 1. Hybrid AMP Page:
// pages/article.js
export const config = { amp: 'hybrid' };
import { useAmp } from 'next/amp';
export default function ArticlePage() {
const isAmp = useAmp();
return (
<div>
<h1>{isAmp ? 'Fast AMP Version' : 'Full Interactive Version'}</h1>
</div>
);
}
### 2. AMP-Only Page:
// pages/about.js
export const config = { amp: true };
export default function About() {
return <h1>Pure AMP Page</h1>;
}
*Note: AMP is not supported in the modern App Router (app/ directory).*
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
