I applied through college or university. The process took 2 days. I interviewed at Nielsen (San Francisco, CA) in Nov 2012
Interview
There was an SAT like test. First round was with one person. Second round was a full day at the office with three people from various parts of the organization. There was a "peer" interview that occurred during lunch. The majority of it was behavioral based. It felt like they were looking for people to fit into their company culture. If you passed the test, it was assumed you had the skills to do the job.
A recruiter started with a quick phone chat to get to know ,e better. Asked about my background, experience, and why I'm interested in the role. Got a few behavioral questions to see if my values aligned with Nielsen’s culture.
An interview followed by an in person case study. The process was fairly straight forward but the case is not easy if you are not an analytical person to begin with.
I applied online. I interviewed at Nielsen (Kuala Lumpur)
Interview
It very easy. Basic question are asked. They ask what did I work as in previous company and how I can contribute to current role. Ask why I want to join the company.
