The hiring process is very long. They take you through several rounds of interviews and conclude the process with several presentations. This is a very important position in that company and so you should be able to sell yourself well.

They quiz you with some image processing problems which can be answered with some common knowledge. They give you problems which can be solved by using some technical algorithms. They have a technical round where they quiz you on your majors. The questions depend upon who interviews you. It is just the same team members quizzing you on your major's subject.

Image processing algorithm based questions were difficult during the time of my interview. But later when I thought about it, it was not unsolvable without prior knowledge in that subject. I needed to be very analytic.
