I applied online. I interviewed at Nokia in Feb 2020
Interview
It consists of 2 parts: one through telephone abotu technical things. Second part is face to face (or via skype right now I guess) and there are questios both about HR issues, as well as technical specifics. The st part lasted 30 minutes, 2nd one more than one hour. They respond quite quickly.
I applied through an employee referral. The process took 1 week. I interviewed at Nokia (San Diego, CA) in Jul 2014
Interview
There was a panel of 4 people who interviewed me, and 2 people at each time. And they asked mix of technical and behavior questions. They are very friendly and tried to guide me to give them the answers.
I applied online. The process took 1 day. I interviewed at Nokia (New Providence, NJ) in May 2017
Interview
Rather then them giving you questions, they wanted questions from you. It was more of tour then an interview but there were several people from a team that interviews you. One of the 4 people asked about my senior project in college so I gave an in-depth responce about it but overall the process went pretty well. Definitely a behavorial interview rather then technical.
