I applied through an employee referral. The process took 4 weeks. I interviewed at Nokia (Dublin, Dublin) in Nov 2015
Interview
its a one day interview on site, and you may also have some phone interview before that.
you will meet many team members, managers and HR.
its from 10am to 4pm and the most important part of the process is the candidate talk.
Interview questions [1]
Question 1
a) candidate talk: present an hour long session about your recent project/research
b) meet individually with team members/managers/hr
*questions are usually very general and high level, and there is no problem solving questions.
