Interview Q/A Page for Defence Research and Development Organisation (DRDO)

1. What is your previous experience?

Answer: My previous experience includes working on projects related to my field of expertise and collaborating with team members to achieve our goals.

2. Can you tell us about a real-world problem you have solved?

Answer: Yes, I have worked on a project where we had to develop a solution for a technical issue that was affecting our company’s operations. We were able to successfully implement our solution and improve the efficiency of our processes.

3. What are your core subjects?

Answer: My core subjects are related to my field of study and include topics such as communication signals and signal processing.

4. Can you explain the stress-strain curve of cast iron and show the yield point?

Answer: The stress-strain curve of cast iron shows the relationship between the stress applied to the material and the resulting strain. The yield point is the point at which the material begins to deform permanently.

5. What is 1st angle projection?

Answer: 1st angle projection is a method of orthographic projection used in technical drawing where the object is placed in the first quadrant.

6. What are the various loads acting on a car while it is moving on the road?

Answer: The various loads acting on a car while it is moving on the road include gravitational force, air resistance, rolling resistance, and inertial forces.

7. What is composite and why have composites replaced metal?

Answer: A composite is a material made up of two or more different materials that, when combined, produce a material with unique properties. Composites have replaced metal in many applications due to their high strength-to-weight ratio, corrosion resistance, and other advantageous properties.

8. What is the voltage formula?

Answer: The voltage formula is V = IR, where V is voltage, I is current, and R is resistance.

9. What does INS stand for?

Answer: INS stands for Inertial Navigation System.

10. Can you tell us about your knowledge of mechanics?

Answer: My knowledge of mechanics includes an understanding of fundamental concepts such as force, motion, energy, and work, as well as their applications in real-world scenarios.
