BARC ECE Actual Interview Questions & Experience
The interview panel at BARC asks questions from the following subjects: network theory, EDC, digital, control, and analog circuits, electromagnetic field theory, communication systems, and signal and system theory. The panel will ask questions specifically related to these subjects, but they will go into great detail. This depth of questioning can focus on either theoretical or practical applications of the subject matter. Therefore, be prepared for unexpected and challenging questions. The panel is known to be very supportive and will offer hints to guide you. If you are able to articulate your ideas effectively and possess a strong understanding of the subject matter, then you have a good chance of succeeding.


  1. Asked about M. Tech Research Topic?

  2. They started asking me about CDMA, I answered, and then they ask about spreading Technique?

  3. Next, they ask, "How do you spread code. I explained on Board, and then he gave me one situation if 2 users are there, how will you assign code.

  4. Then they ask me about serial data communication. Difference between synchronous and asynchronous data transfer.

  5. For serial to parallel conversion what digital circuity used?

  6. Next, they ask on power control in spreading code?

  7. After this next person start asking electromagnetic field theory they started asking system noise temperature, Antenna temperature?

  8. What is figure of Merit of Antenna?

  9. Which Antenna preferred on transmitter side and which used in Receiver side?

  10. They told me we guess you have enough command over communications EMFT but you have told is an also comfortable in Analogs Ede, I told yes sir.

  11. Then they ask can photo diode work as an amplifier?

  12. What are the materials other than silicon and Ge to make photo detector device?

  13. After this they ask me about application of photo transistor?

  14. They ask me draw some RC Network, I draw one RC combination and then he gave me square wave and asked to draw output waveform?
