Top 5 Project Viva Questions & Ideal Answers
Q1: What is the main innovation/novelty of your project?
Ideal Answer: "Unlike traditional existing systems that require high latency cloud computation, our architecture executes inference directly on edge microcontrollers with local caching, reducing latency by 70%."
Q2: Why did you choose this database over alternatives?
Ideal Answer: "We selected PostgreSQL/MySQL for its ACID compliance and relational integrity, which was critical for transactional accuracy in user authentication and audit logging."
Q3: How did you handle project testing & edge cases?
Ideal Answer: "We performed unit testing on individual core modules, boundary value analysis on user inputs, and stress tested API endpoints under simulated load."

5 Mistakes to Avoid in Project Documentation
- Missing DFD Level 1 & 2: Always provide Data Flow Diagrams beyond Level 0 context diagram.
- Uncited IEEE Base Paper: Ensure your literature review cites at least 3 peer-reviewed IEEE papers from the last 3 years.
- Low-Resolution Screenshots: Use crisp vector or high-DPI screenshots in your testing chapter.
- Ignoring Future Scope: Examiners love to ask how this project can scale in production.
