I am Arjun, I have attended the Power grid interview on 3-Nov-2008 at Bhubaneshwar. I like to share some of the questions that I have faced in the interview.

The Interview panel comprises a team of 6 persons, as this interview is for the post of AE to work under Rural Electrification projects in the states of West Bengal and Orissa, apart from the Technical skills they looked for knowledge in Hindi also. As the work comprises mostly of construction of Distribution sub-statation and Distribution of the supply. They very much concentrated on the Power systems and they also posed questions in the Power Electronics.

On an average the interview will go around half-an-hour as said earlier they looking for both Hindi and Technical skills in the Candidate. I am posting some questions here which I have faced in the interview. Hope it will be useful for the people who are atteninding the interviews.
