Need Help For Cracking Robotics Interview

Hello everyone,I am studying engineering in Electronics and Telecom discipline. I am fond of robots since my childhood. I have small doubt i.e. if I want to get placed in robotics / automation based company ,what should I study(reference books/software etc) particularly for cracking an interview ? In simple words,as electronics engineer what other specific skills (like embedded C programming etc) should I go through? Can anybody suggest something.Thank You ;-)
