Nielsen Field Representative interview questions

I initially posted for the position on the Company website. It was around two weeks for the first contact from an hr rep, an email to set up an initial phone interview. The phone interview was very basic with simple factual questions. I was given the date for a group critical thinking assessment. Not bad, only thirty minutes to complete. It was then followed by a 3:1 interview and then a 2:1 interview at the regional office.
