I applied online. The process took 4 months. I interviewed at BITS (Pilani) in Jul 2016
Interview
There were 3 steps. The shortlisting is very tough and they shortlist candidates with exceptional background only with foreign experience (Post Doc.) (At this moment as many people are applying). There will be a departmental interview followed by the final interview where minimum 8-10 people will be present including senior management.
Interview questions [1]
Question 1
Technical and as well as HR questions are common. As the experts are from IIT or IISC expect area-specific research questions.
