Got the first online interview through my university. That interview was a 30min talk with one of the technical leads about my experience, knowledge, and interests. I then got an email 2 hours later with an invitation to "Cisco Day", which was 3 interviews at their Raleigh campus. Food and travel expenses were completely covered. The first interview was a behavioral interview with a technical manager. He also gave me puzzle questions. For example the 8 balls with one heavy ball and a scale problem (Google it). The second interview was a one on one presentation that was asked to be prepared when I got my invitation. The third interview was a technical roleplay where I was questioned heavily on network information. That day felt more like an advertisement for Cisco rather than an interview.
