Interview Experience
FIRST Q. WAS
HAVE YOU PREPARE FOR INTERVIEW?
I ANSWER TRULY ..SORRY SIR , MY FINAL YEAR EXAM JUST OVER YESTERDAY. I DID NOT BRUSH UP A SINGLE SUBJECT BUT I AM STRONG ENOUGH IN BASICS OF ALL ELECTRONICS SUBJECT AND ALSO MY FINAL SEMESTER SUBJECTS.
WHAT IS YOUR FINAL SEMESTER SUBJECT???

I TOLD.
1. VLSI DESIGN
2.MOBILE COMMUNICATION
3. TV AND RADAR
4.ADVANCE COMMUNICATION

They give one wave form and asked basic parameter use in it.
i don't understand question and try to solve. Then they give me lot of hint, through hint my mind grasps what they want to asked I explain. but this time some less confidence.

MY INTERVIEW WENT FOR APPROXIMATE 2 HOUR. I WAS THE SECOND CANDIDATE IN 10 STUDENT WHO GOT MEDICAL SLIP.

Technical Interview
Round 1

Technical Interview

Interview Questions
  • Question 1: draw an amp with gain of -10 and gain of +10
  • Question 2: Is this gain fixed or variable, what is the purpose of resistors?
  • Question 3: draw the LPF as an active part of the circuit
  • Question 4: They asked to draw Bode plot and give magnitude at cut off frequency.
  • Question 5: gave a common mode op amp circuit and CMRR asked me to get the common mode gain
  • Question 6: They asked to design a dynamic A to D converter with pass band of some Khz only block diagram.
  • Question 7: Design a circuit to get the distance between two TTL pulses in micro sec?
  • Question 8: They asked me to explain the operation of a quantiser
  • Question 9: Design a oscilloscope with two channel digital display system operation of switch as transistor
  • Question 10: MUX types and operation.
Interview Experience
1. draw an LPF ?
I drew a passive LPF followed by active op amp
2. draw the LPF as an active part of the circuit
I drew a cap in the feed back path along with R
3. When they gave a common mode op amp circuit
and CMRR asked me to get the common mode gain ( was helped here but got the ans - its like u have to find the diff gain by superposition)
4. design a circuit to get the distance between two ttl pulses in micro sec?
(counter with toggle flip flop-I missed the toggle flip flop here..it is used to set and reset the counter by the two ttl pulses )
my interview was for 70 min and was not given the medical slip

Technical Interview
Round 1

Technical Interview

Interview Questions
  • Question 1: Questions on my 5 subjects of my choice - Network Theory, EDC, Digital, Controls, Analog circuits
Interview Experience
First there was documents verification. We were given a form to fill details. After documents verification is done they call you for interview.

My interview lasted for about 1hr15mins.
They asked me which were my favorite subjects....(u need to tell 5)....mine were
Network Theory, EDC, Digital, Controls, Analog circuits........
They asked questions from these subjects only. On the whole it was a good experience. The panel is very cooperative and give you ample amount of hints. if you can present your ideas well and have good subject knowledge, then I feel you can make it. If u do well then you are given medical examination slip, which means you are selected for sure.

what happened to me was.....after the interview i was asked to wait for 2 minutes(i dont know what happened behind the door) after that i was asked to leave. I did not get the medical test slip.
any ways. Thats it from my side. All the best
Interview Tips
They go in depth and it can be subject oriented or practical application oriented. So be prepared to encounter some surprising questions

Round 1

Technical Interview

Interview Questions
  • Question 1: They gave a network n have to find current through particular resistor at t=0+;0-; t infinite(transients problem)
  • Question 2: equivalent potential btw two points 4 given network.
  • Question 3: They gave i/p and o/p wave forms. We have to design circuit(clampers problem)
  • Question 4: they asked about pll diagram;lock range,capture range which is greater??
  • Question 5: In digital probs on counters (practical Qs);flash type A-D conv block diagram.
  • Question 6: some Questions on micro processors 8085,8086 data lines,address lines,address locations,some programs etc
Interview Experience
first intro(2 min)
Then they asked my fav subs.
I said networks,controls,communications,digital.

Overall the interview was easy but I didn’t prepare for interview.
They are very cool and helping(8 members in my panel)
On that day out of 16 people from ece, one person got medical slip.

Round 1

Technical Interview

Interview Questions
  • Question 1: : how to make a voting system such that a maximum of 1000 voters are there and at the end of the voting the system should indicate who won among the two candidates.
  • Question 2: they asked where to connect the buzzer for voting.
  • Question 3: 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.
  • Question 4: 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.
  • Question 5: At last they asked me to build the voting system using 8085 up. just draw the hardware.
Interview 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.

Interview 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....

Round 1

Technical Interview

Interview Questions
  • Question 1: 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.
  • Question 2: gave me various circuits and have to find the vout waveform if input is A.C.
  • Question 3: Was asked theoritical questions in optical communication.
  • Question 4: About the duality concept and it basic blocks and many more similar questions.
Interview 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.
Interview Tips
You just need to be confident, best of luck all of you.
