BEFORE GIVING ANY PSU INTERVIEW I SEARCHED A LOT FOR THE QUESTIONS ASKED BUT I ALWAYS GOT INSUFFICIENT QUESTIONS. SO THIS IS MY ATTEMPT TO BRING YOU PERSONALLY EXPERIENCED QUESTIONS. I ALWAYS UPDATE IT BY GATHERING INFORMATION FROM FRIENDS TOO.

SO DO COMMENT AND FOLLOW ME FOR MORE EXPERIENCES AND VARIOUS INFORMATION.

BARC SCIENTIST INTERVIEW

Friday, December 28, 2018

⏩BARC (Bhabha Atomic Research Center), Mumbai.




   This is an interview of a candidate who is selected as a scientist in BARC. His name is Abdullah Abdurrehmaan. He got medical slip i.e. got selected. Out of 66 people, 5 were selected that day. A BARC scientist candidates interview lasts for at least 1 to 1:30 hours though you know anything or don't know. They politely but completely examine you.
   Let's hear in his own words.


   I have two years of experience in R&D they asked me related to that and argued for around 15 min.
  Then they asked my five favorite subjects. 

1. Op-amp .
2. Digital .
3. Electronics devices and circuits.
4. VLSI.
5. Communication.
  
   They started with some simple ckt but then they kept asking till I require some hints.
 Then they started again with 
Integrator,
Drawbacks of a simple integrator.
Practical integrator.
What if a constant current is used.
Draw frequency response.
Pole-zero plot.
Given some input and asked to draw the output.


  Then they gave me some pulse then asked me to design a digital ckt to expand it 10 times then they asked alternate methods and lots of counter questions.

   Then on transistors, all configurations of CE amplifier s. 
Effect of resistance Re on the gain, stability, frequency etc.

   Then on specification sheet of BJT, for such parameter what condition comes in to picture. They questions on the gain-bandwidth product for 15 minutes.
   Then they asked me to draw 3 integrators connected in a loop ( i could recognize it as RING OSCILLATOR). 
The output of ckt frequency, drawbacks, and uses.



 Then they asked about oxidation processes and what if we want more oxide layer.


Some indirect questions on the advantages of modulation, wired and wireless communication.

   Few of them highly impressed and they appreciated that I remember a lot of things even after two years, I told them that I used to help juniors to solve their doubts.

For the questions which I was not confident, Simply confessed that I haven't come across and I have no idea about it. So be honest and do comment if it goes out of reach but no silly answers and stick to the basics.
