There were two interviews. The first interview was at the school campus. There were two interviewers, spent 30 mins with each. First asked questions about Linux command lines. The second asked about programming. The questions were meant to assess understanding, not be brain-teasers like some interviews. The second interview was at the Cisco building. Not as many questions asked the second time around. It was more about meeting the team, seeing the building, and having another team member confirm competency.
