Example Question: "How do you handle authentication securely?"
Here is how a top 1% candidate answers this: "JWTs for stateless auth — short-lived (15 min). Refresh tokens in HTTP-only secure cookies (not localStorage, prevents XSS). CSRF tokens for state-changing requests. Rate limit login attempts. Implement MFA for sensitive operations." This answer works because it is specific and structure-driven.
Example Question: "Design a real-time chat application."
Here is how a top 1% candidate answers this: "WebSocket (Socket.io/native) for bidirectional communication. Message queue (Redis Pub/Sub or Kafka) for fan-out to multiple servers. PostgreSQL for message persistence with conversation partitioning. Redis for presence/typing indicators. CDN for media attachments." This answer works because it is specific and structure-driven.
Example Question: "How do you decide between SSR, SSG, and CSR?"

CSR: highly interactive SPAs behind auth. ISR (Incremental Static Regeneration) is the sweet spot for many use cases." This answer works because it is specific and structure-driven.
Example Question: "How do you handle a low-performing team member?"
Here is how a top 1% candidate answers this: "I start with a candid 1:1 to identify the root cause (skill vs will). I set a PIP with clear, measurable goals and weekly check-ins.
