PowerGrid Interview Experience for Assistant Engineer Trainee (GATE-CS 2022)

The interview experience was excellent. That was the first interview, I had ever given. The major focus of my interview is on the Computer Network and Network Security part. I will explain my whole experience step-by-step:

Firstly, I had received a mail that I am qualified for the interview and the venue given for the interview was POWERGRID Corporate Office, Gurgaon. I have gone there in the formal dress which has a plain light cream shirt, black pants with a black-tie. They checked the interview call letter at the entry gate and they took us to the Conference Hall. Then we were told to take the psychometric assessment over the mobile phone on the link that they had forwarded. There is document verification going on there parallelly. After completion of verification, they sent a group of 6 people for the GD. They gave many topics and the group agreed on “Advent of E-Learning“. They had given 1 min for thinking, 2-3 minutes for discussion, and 2-3 minutes for writing about it.

After all this, they sent all of us for interviews one by one. Here is how my interview went:
