- Q1. If in a room we have to maintain temp. b/w 25 to 28'C. means for less than 25 the heater should be on automatically and for more than 28 the ac should be on.so make a circuit for this
- Ans.
A circuit to maintain temperature between 25 to 28'C by automatically turning on heater or AC.
Use a temperature sensor to detect the room temperature
Connect the heater and AC to a relay module
Use a microcontroller to control the relays based on temperature readings
- Q2. Gave me various circuits and have to find the vout waveform if input is A.C
- Q3. Was asked theoritical questions in optical communication
- Q4. About the duality concept and it basic blocks and many more similar questions
Interview Preparation Tips
Experience: there were 6 people in my panel.
Then they asked me my preference subjects:
network,
electronics,
digital
,signals,
controls.
overall interviewer was good.it went for 1.5 hr it was a discussion rather than a interviewer.
They give you lots of hints and you have to just catch those hints and give the answer.
They are checking ur analysis part rather than your theoritical knowledge.
Tips: You just need to be confident, best of luck all of you.

- Q2. They asked where to connect the buzzer for voting
- Q3. They give me a circuit involving a voltage source some resistors in parallel and series and then an ammeter connected in parallel to some resistors and asked me the ammeter reading I answered correctly
- Q4. Then started the problems they asked me what are the stages of an opamp but i couldn’t recollect...i said differential amplifier, ce, cb, cc and lost my point there
- Q5. At last they asked me to build the voting system using 8085 up. just draw the hardware
Interview Preparation Tips
Experience: my interview lasted for 1 hour.
I was the first went inside and the interview board was very friendly. There were 6 of them and asked me to write my 5 preferred subjects in order...I wrote
opamps,
network theory,
digital,
analog,
8085 uP.
Tips: best of luck for you all....they will help you a lot ...try to get the clues correctly from them and apply in the problem given....
Skills: 8085 up, Analog Communications, Digital Communications, Network Theory, Op-amps
