Cisco Software Developer I interview questions

I was initially interviewed with a quick phone screen. Just some C debugging questions. I flew through it. Was later invited for a telepresence (Cisco's proprietary video conferencing system) interview. I only had to go to my local cisco office while my interviewers were in California. There were 3, 1:1 interviews. One by the project manager, then by a senior manager and then by a software engineer. The first was resume based, plus some HR questions. The second was purely resume resume based plus some knowledge questions. The third was purely code based with some C questions. (Pointers and stuff) The manager called me the next day to let me know I was selected!

got the interview through a referral. the interview process consisted of a technical onsite interview with five people. First interviewer was very thorough and went through everything on my resume and asked me many questions on extra activities and not on coursework. Second interview was a skills test and comprised of questions like diffrence between a mutex and semaphore. which data structure to use in what situation etc.
