As soon as I entered my panel the interviewers started asking questions from Mathematics. Mostly topics from linear algebra, definitions from vector and matrices, their applications etc. I couldn’t answer those as mathematics is not my strong subject. I didn’t study Maths while preparing for GATE as fewer questions from Maths are asked. If I have to advise one thing, it would be to not neglect Mathematics.”
