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 ( SELECTION THROUGH EXAM) DAE

Friday, December 28, 2018

⏩BARC (Bhabha Atomic Research Center), Mumbai.

Interview Date: 9th July 2009. 
DAE➝ Graduate fellowship scheme for engineering graduates.


One of my friends is sharing the experience.
   I was the first person to be interviewed and was quite nervous. When I entered in the interview room the panel members (5) greeted me warmly.
   One of them asked me to hand over my marksheets so that he could have a look and also took the project report I was carrying. After the initial inquiries...Background, how was the written test etc. Then asked me to write down five subjects of my interest.
   

One of the members started with Analog.
1. Draw a basic CE amplifier.
2.function of all the capacitors i.e. coupling bypass.
3. Explain how you can say emitter terminal is common whereas Re is connected.
4. What is the gain of this amplifier?
5. Why potential divider biasing?
6. What is Q point?
7. Draw the load line, explain it's characteristics
8. How do you get various regions.?


Then they proceeded to Opamps and spent a lot of time on it.
1. Asked to draw a basic Opamp amplifier.
2. What is it's gain ...Derive it.
3. What is a virtual ground?
4. Can you prove that both are at the same potential? 

One of the members given a problem on Opamp and asked to draw output...Gain and input were given...

One more on CMRR concept. Then proceeded to Precision Rectifier. I got stuck here while drawing the ckt. Got some hints but I realized that made some mistake s.



They moved to Diode...All the basics of the diode ...One question on the resistance of the diode.


In Digital ...Asked to design a counter, so many questions regarding counter. Asked about ADC and DAC.

The interviewers are very helpful in nature, provide so many hints, they will literally get you to the answers. I got nervous after 50 minutes in the interview and was offered tea and water. Any way...Towards the end ...Last half an hour... Questions focused on project and power electronics. I felt I had done better in this half an hour. Was actually feeling quite bad when I couldn't by hi Dr. Because questions were so logical and valid.

After the interview, I asked to sit outside for five minutes. I was stuffing all my mark sheets and was preparing to leave. A ma'am came and given me the medical slip... I was on the seventh heaven... I got selected...
