Cisco Developer interview questions

The HR keeps asking about what courses I have taken in my graduate study. I list some courses about computer engineering. It seems she is not satisfied with that. And she asked me again about what other courses except the CS course .... And she also asked why cisco, why chose cisco and why should cisco need me

Flew candidates out to Cali. Went through three rounds of interviews 45 mins each. Went over what was on my resume, some basic programming questions like linked lists, and also some intelligence questions like how many weighs do you need to know what is the bad ball out of 8 balls.
