2 day interview process, they flew in 2 staff from norway, consisted of group activities one day and individiual assessments the other. The group activities were not of an engineering background and consisted of moral and ethical situations with a 20 min group presentation. The whole time we were monitored by 3 to 4 recruiters. The other day consisted of individual activities with a 45 min two ion one interview. The questions were based more around an informal getting to know vibe. They werent technical and didn't try to trick you. Took us out for an informal dinner aswell after the first day. The whole process was enjoyable and didnt feel to pressured, however the sheer time required (two days) was probally more then needed.
