What are common mistakes teams make with Components when using MERN Stack?

Short answer: Interviewers want a crisp definition, a practical example from your projects, and awareness of trade-offs—not textbook dumps.

How to structure your answer (60–90 seconds)

1. Define Components in plain language for MERN Stack.
2. Context — where it appears in a typical Frontend project.
3. Example — one sentence from work, internship, or a practice app.
4. Trade-off — what you gain vs what you sacrifice.

Real-world example

Describe a feature you built, the constraint you faced, and the design choice you made.

Step-by-step talking points
