The process took 1 day. I interviewed at Nokia in Aug 2008
Interview
It was not very difficult. Just plain question of 3G mobile networks structure, SS7 series (both core network and access network) protocols and previous project experience. Only 2 interviewers in total. One of them is the project manager, the other is the hiring manager.
Interview questions [1]
Question 1
