they basically drive the questions in a way which the candidate takes it. In my case, it started with a simple block diagram of analog communication circuit, and moved to LP filter. Then, to BPF analysis and digital communication. Unexpected question was where i see myself 5 years down the line. I was not prepared as it was a technical and my first interview.
