Cisco Software Engineer interview questions

Got a interview after a job fair. It was my first interview and I feel I blew it.

I submitted my resume through Cisco.com for a Software Engineering internship position. It took about a month for them to contact me back. The recruiter called me for a phone interview, the questions were pretty easy. It's more of a review of my resume and background. I was called into an onsite interview about a week later with the hiring manager. The questions were pretty easy, I guess it was because I was applying for an internship position. He asked me basic PHP questions, how does web application works, some networking fundamentals and some design questions. Then, I was interviewed individually by the entire team and extended team. It was a pretty long 5 hours interview. The interviewer were really nice and took a lot of notes during the interviews. You should really study and prepare for the interviews in both technical and soft skills questions. They offered me the internship about two weeks later.
