The process started with a set of 2-3 highly tecnical phone interviews, all with people that were currently in the same position I was applying to.
Then a set of final interviews on site, which actually weren't on site because I couldn't travel, so they arranged a video conference to do the interviews.
The last round of interviews were with 2 people that were currently in the same position I was applying to, and also 2 managers.
The topics of the interviews were general knwoledge of networking, linux command line, windows and Mac OS X configuration issues.
