Cisco Software Engineer interview questions

One round of aptitude followed by 2 technical rounds and one HR round. The apti mainly consisted of questions on permutations. Technical aptitude had questions from c and logic design and networks. The 1st round of interview was almost 1hour 15 mins!!! Covered details of C and Networks and a few programs. Second round had questions about scripts. HR round was typical

Went to career fair, afterwards called me for an interview. was asked some basic questions about programming, and some brain teasers, pretty simple.
