I applied in-person. The process took 1 week. I interviewed at Nielsen (Dallas, TX) in Jan 2014
Interview
The hiring and interview process were both easy and smooth, interviewer was kind and unintimidating which made you feel very relaxed and helped you answer questions. They did not take long to get back about an offer.
Interview questions [1]
Question 1
How you would keep someone on the phone if they were reluctant to complete a survey?
