Hello Friends, I’m Amey Das.
Currently, I am working as a Scientist (Gazette Officer) at DRDO (Defence Research and Development Organization). DRDO is one of the best PSU in the research and development sector in India.
I got call from DRDO interview through the GATE score. I attended this interview.
So, on this DipsLab platform, I am sharing my interview experience and technical questions.
DRDO Interview Questions | Personal Interview
At that time, there were five members including one chairman present. Every member asked technical questions subject-wise.
My interview started with chairperson. As usual interview, he started with some personal questions.
- Briefly introduce yourself.
Answer: I answered all about myself, qualification, B.Tech project, and other basic educational details. If you are fresher, you should be well prepared for the B.Tech project.
- Tell me about one practical you performed in your BTech.
Answer: I shortly explained the open and short circuit test of a single-phase transformer. This is machine lab practical.
- Why do you want to join DRDO?
Answer: Explained my working interest, future plan, and other reasons. I tried my best to answer this question. I think, they were satisfied with my answer.
