What's your experience of attending M.Tech (nanoscience and engineering) interviews at IISc Bangalore?

My friend has the opportunity to attend MTech inter rhe at IISc Bangalore. She was called on the first day itself where she sat waiting and was eventually summoned.

As she entered the room, the panelists asked for her introduction. They bombarded her with both technical as well as non-technical questions. The non-technical ones looked like

• What made you choose nano-technology?
• What do you know about nanotechnology?

They kept counter-questioning her based on her answers. Following this was a round of technical questions. I have only mentioned the most important ones

• In the current times our electronic devices are becoming smaller, so what do you think?
• Draw the MOSFET structure on the board. The problems and the solution pertaining to it. 
• What is the fastest bus? 

The interview lasted for 40 minutes. What she learned from her experience was that you need to focus on your basics while preparing. Also, try to answer them honestly because they will counter-question you. She was also surprised that they did not even care to ask a single question about Math and the whole interview was a new experience.
