Online assessment: how my previous experience would help me to succeed in the new role, why do I want to work for Nielsen. Face to face: very long and detailed interview. Interviewers were well prepared, passionate about their jobs and extremely experienced. I had several questions about my presentation and also competency based ones. Eg: how do you work under pressure? Tell us an example of when you had to reach a tough target and how you achieved it, tell us an example of something you did that improve something in the company, if lots of people are asking you things with a short deadline, how do you prioritise it, how do you face changes etc.
