    Hi,
    I’m Suraj & My Branch is Electrical Engineering.

    I am sharing my interview experience. There were three people for taking the interview. There was one HR and two sirs to ask technical questions.

    First of all the HR asked my introduction like qualification, interests strength, about family background, internship training & your final year project. He asked all these at once, then I answered all of them.

    Then another sir came to ask technical questions and he asked me in which language I would like to give the interview? I told sir both Hindi and English (Hinglish), then he asked me about my favourite subjects. I said power system & renewable energy sources.

    Then he asked all the questions asked from
    Power System like –
    WHY TRANSFORMER RATING IN KVA?
    WHAT IS TRANSMISSION LINE?
    WHAT IS CABLE IN TRANSMISSION LINE?
    EXPLAINE IT.
    What is insulator & insulation tell difference between them.
    What is the maximum voltage that can be transmitted in transmission line? I replied then he told in the power project of his company that we are transmitting more power in this also..

    then he asked about the substation like what is lighting arrester in substation?

    Then second technical sir switched and asked what is electrical circuit? types of circuit. He just asked one question,

    then HR came and asked are you ready for relocation, I said yes sir, then he asked me to leave and then the interview ended.

    So overall my interview went very well, I had answered 95% of the questions but I got a bit nervous while giving my interview, so maybe because of this my points would have been reduced and that is why I got the selection mail late, after almost 1 month. I was put on hold even after the interview went well.

    So those who have not got any result after the interview, please wait, if the interview goes well then you will definitely get the selection mail.
    ALL THE BEST.
