How is the personal interview in IIT Kanpur for M. Tech selections?

One of my friends had appeared for VLSI MTech personal interview at IIT Kanpur and shared his experience of the same.

He was interviewed by 2 professors and one of them asked the reason for his poor marks after the first year. My friends told him about his lack of interest in the field and no core companies making it to the company for placements. He had decided to prepare for GATE instead and managed to get AIR 197 in his final year.

Next, they asked him some technical questions related to the EDC portion. He was even asked to draw a logarithmic plot of current v/s voltage for a practical diode.

Next, he was asked questions from the analog portion, which he hadn’t prepared well. To his relief, they asked him only basic questions like he was asked to identify a configuration. He wasn’t able to answer a few questions related to analog and concluded that it’s very necessary to revise your concepts even after GATE.
