Cisco Software Engineer(Internship) interview questions

I got a call from University Recruiting and had a WebEx interview. It was a 1-hour interview. The interview wasn't hard. You need to be confident and not make any simple mistakes. I made a few basic errors.

Met the recruiter at the career fair, got invited to an interview the following day. The interview was easy, all behavioral questions, they wanted to know how well you work with teams. The interviewer was very nice and the whole interview was very relaxed. After the interview, the interviewer introduced me to another recruiter from Cisco next door and she asked me some brief questions about my skill (what programming languages do I write, what are my interests). The interviewer said he'd email me later the same day, but never did. A week later, I received an email from him asking for another talk on the phone, but he never replied after I sent him my available times. Neither the interviewer nor the other recruiters replied to follow-up emails, and I got the rejection letter almost a month later. Overall, interview process and interviewer were all very nice. But not replying to any emails afterwards was kind of frustrating.
