First stage I had a HR interview over the phone verifying my resume, interests and my qualification. There were some basic questions, which dint need any preparation. Second round, a technical interview was scheduled over the phone, which lasted for an hour and had basic question on Control systems, Matlab, Simulink, C, programming concepts, calculus and high school level physics. Most of the questions were straight forward, but I believe my application was rejected because of my poor knowledge about C programming.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
