I applied in-person. The process took 1 day. I interviewed at Nielsen (Wilton, CT) in Jan 2015
Interview
Had an over the phone interview and then went to the office one week later. Questions were mostly behavioral and some critical thinking questions. One brainteaser. Overall, was very nice and professional. Also got a tour of the office.
