Cisco Developer interview questions

it was a campus recruitment. my interviewer was cool, gives you time to think, so don't be tensed.

They had 3 rounds of personal interviews once I cleared the written test. First interview was totally based on computer Networks. He asked me some basic concepts of Networking. Second interview was based on my CV. He asked me few questions on data structures, about my projects etc. and the third was the HR interview and the main questions were why cisco? and would you like to go for masters or not??
