BARC ECE Actual Interview Questions & Experience
The interview panel at BARC asks questions from the following subjects: Network Theory, EDC, Digital, Controls, and Analog circuits, Electromagnetic field theory, communication system and signal and system . 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. They have asked us to make a PPT on research objections and methodologies. They first ask about that PPT. And most or question. They ask from my major project (Research Topic-M.Tech.)

  2. Then they said, it seems you have done more theoretical analysis than practical work. [1 agrees that it was a simulation-based project.

  3. Next, they ask about senses. How do seniors sense the environment? I answer then. Next, they start asking me, "Currently, do you think we are using any of these sensors in conversion?"

  4. Next, they ask, since your project is related to communication. Is wireless communication secure for high security applications like the military?

  5. The next question they ask me is about Gaussian noise. 1 answered, then they asked further: "When we receive some signal, how can we determine that Gaussian noise?" is associated with it. I tried to answer, but they asked me to elaborate practically.

  6. Then, next, they asked me about precision and accuracy. Why are they both important, and are they related to each other or not?

  7. They were more oriented towards practical questions, and they wanted the candidate to also follow a practical approach while answering.

  8. Next, they ask, "Is encryption possible in senior communication?"

  9. Next, they ask, "What do you think of object detection?" Can you design the layout of a prototype model of any object detection system?

  10. What is an antenna? I answered. Next, they asked, "How can we determine the maximum and minimum strength of the signal by antenna practically?

  11. Then next, they started asking about the signal-to-noise ratio. They next asked about the matched filter and how it was working. Practically, how is it designed and how does it maximize the signal-to-noise ratio?
