Cisco Software Engineer interview questions

I did my summer internship at Cisco this year, for Internship there were two telephonic rounds. First one was technical round, all questions were from Data Structures and Object Oriented Programming Principles; second round was an HR Round where they asked me about my interests, family, etc. During the internship I applied for Full time job, where they took one written round, which had 50 questions (20 Math/MAT, 30 Technical) and was supposed to be done in one hour. Technical questions were from Digital Electronics, Computer Architecture, and Microprocessors/Microcontrollers. After written round there were technical, manager and HR rounds. In Technical round they asked me questions from my Projects, Data Structures and Sockets, Manager round had few technical questions and brain teasers, and HR round had questions like why I want to join Cisco, etc.
