the first round was a recruiter call; the second round was a hiring manager interview; the third round was 3 back to back interviews; it's one of my best interview experience

I only interviewed for my first Cisco Internship, and it was just one coding question in an IDE and language of my choice. Back then I only knew java, so I opened up eclipse and coded out what I could. I wasn't able to answer the question, but talking through my thought process definitely helped.
