5 interviews in one day. Technical one was very difficult. Some questions were even at CCIE level, even though this was not mentioned in the job requirement. Many Questions related to BGP and how to troubleshoot network issues.

It was pretty good. Initially, there was a hiring manager interview who spoke about the company, position, and salary expectations. After a week a call was scheduled from the team member, went really well. I received good feedback, then a final round was scheduled with 4 interviews two technical and two on leadership skills. Both the technical interviews focused on linux and projects I have worked on including the leadership skills as well.
