There weren't many difficult questions. They were mostly relevant to telephony. I answered them in depth as possible for me. The job deals with protocol stack from top to bottom. (which was not mentioned as a requirement though. ) I was familiar with mostly layer three and my answers were limited to that perspective. They expected details across the layers of protocol stack.
