I applied online. I interviewed at BARC (Mumbai) in June 2016
Interview
it is lengthy and very conceptual questions are being asked.the interview lasts for minimum 45 minutes.....after successful interview they will hire you as per your merit.....there are on an avg 30-50 seats
Interview questions [1]
Question 1
they at first ask what are your favourite subjects
Tough only technical interview from basic to deep. You can be wrong also but conceptually you should be right your knowledge is checked your way of answering the question is checked
