Cisco interview questions

Initial round was a written test consisting of 20 Aptitude and 30 Technical (Networks, Digital Logic mostly) questions. Next round was a Techhical Interview. Questions asked ranged from explaining about previous Projects undertaken to explaning some algorithms (search/sort etc). Some also involved about the programming language you were mostly familiar with (for ex: C). There were some questions on Networks, OSI layer, switches, routers etc. Math puzzles may be asked. Round following this would be HR.

Spoke to them at campus career fair, scheduled 30 minute on campus interview for the next day. The interview was very informal, talked through my resume, offered an internship a week later.
