I gave the AMCAT exam on the basis of which I was called to for an interview (off campus). There were 2 rounds- Technical & HR. In technical, I was asked questions about my stream of Engineering and some general questions regarding cellular technologies, their functioning. The Technical interview was 15 minutes long. After that there was the HR round where I was just asked how had my experience been. I was also asked about my gap in education. The HR interview was 5 minutes long. There were 1500 candidates of which around 800 got selected. The interviews were really simple, just prove yourself in the Technical Interview.
