I applied through college or university. I interviewed at IIT Kanpur (Nāgpur, Maharashtra) in May 2018
Interview
A professor from IIT Kanpur has come to our btech college for taking the interviews. Students with greater than 8 pointer were eligible to sit for the interview. The interview ran for about 30 minutes.
Rigorous interview process with basic and advanced questions on materials science and engineering. Though it was tough, still basic understanding of subject helped a lot. Self confidence is necessary and to be focused.
