Nokia interview questions

I got 1 tech assessment in premises, the assessment included questions from 3 sectors (programming, networking, unix) after this there was a group assessment with a quiz. Moreover I got 1 interview with one line manager and second interview with a person from HR and one line manager .

I applied online. Barely 3 weeks later, I received an email followed by a call to arrange a phone interview. That was then followed by a panel interview in person at your office in Ghana. A week later a received an email to meet the HR for salary discussion. Had my offer letter 2 weeks afterwards
