DRDO INTERVIEW(JRF)

Friday, December 28, 2018

⏩DRDO ARDE(Armaments Research and Development Establishment),Pune.

Interview Date: 23rd Aug 2018. (JRF).

   One of the best, well-equipped lab. There was an exam before an interview. Total 67 people appeared for an exam from ECE. They selected 15 candidates for interview, in that my number was 5. Here most of the questions asked were application based. 7 scientists were there in the panel. Biggest panel I had been seen till now.

   1. Do you know, what is hydraulic and pneumatic?

I said" yes, hydraulic uses water and pneumatics uses air.

2. What is the main advantage of hydraulic over pneumatic?

I was well known about the pneumatic and hydraulic because of my final year project. Hydraulic can be used to lift a heavy load and it is slow whereas pneumatic is faster but can not be used for a heavy load.

3. What is RFID? 

"Radio Frequency Identification".

4.what will be the range and frequency of RFID?

"Sorry sir, I don't know."

5. Tell me the difference between microcontroller and microprocessor.

I was aware of the answer to this question but due to stress, I could not answer well. I could tell only one difference i.e. system on chip and system in a chip.

6. I have to retain lower bit as it is, what should I do? 

This was a logical question. I was thinking in which context she is asking. I had taken around 3-4 minutes hence they moved further.
Now my confidence level became low. I suggest you don't stumble while giving the answers, be confident though you are not able to give the answers.

7. In what direction CD/DVD rotates in CD/DVD player?

This was a bouncer for me. I replied, " I don't know".

8. Okay, then do you know how the decoding process takes place in that player? 

I was blank this time. "No...!!".

9. What is the difference between BJT and MOSFET? 

I answered," BJT is bipolar, MOSFET is unipolar. BJT has low input and high output impedance. MOSFET has high input and low output impedance.
 This is also one of the favorite questions of DRDO scientists.

10. Do you know, Which type of antenna is used for TV nowadays?

"Yes, it is parabolic antenna".




11. What is the gain of that antenna?

" One formula is there". Actually, I was trying to remember the formula.

12. What is that formula?

" I know, but I can't remember it now..!!"

13. Okay, thank you. 

Hushhhhh....!!! , This was the toughest interview for me. Checkout my Easiest Interview.
