Cisco Software Developer Internship interview questions

I applied to Cisco online during the winter of 2016. I heard back from them around April and we got an appointment for the phone screening set up right away. Questions were basic algorithm questions and some networking related questions which I was surprised to receive.

talk about previous projects describe technical details as much as possible for about 20-25min, then answering questions including coding and basic knowledge about C++ and C. During processing give me some hints and later tell me the best solutions.
