Requires Engineering knowledge. It will be very difficult for those who doesn't have any Engineering background. I was only interviewed twice during my application. The initial exam was very easy but time pressured.

It was smooth. The interviewer was calm. The questions are commonly use. She also willing to listen and help you elaborating your answer. At first she let me tell something about myself, my skills, and she asked some situational problems where I need to make a right decision.
