My NTPC interview experience

It was back in 2010 when I was called for interview at NTPC based on my performance in written test conducted by them. Yes. Back in 2010, GATE score was not considered for interview call in PSUs (IOCL was the only one who started it then).
Ok. here I am going to post my experience of facing NTPC panel. The interview was conducted at PMI, Noida.
