Nielsen Intern interview questions

I was recruited after one interview by the team I am going to be working for. Team manager, Client Representative and a Business Analyst came to the interview. It was a friendly environment and they were more like chatting and asking about my background, university life and courses. They also asked about my knowledge about marketing research. One of the most important thing was to be long term, start as soon as possible and be able to continue part time 2-3 days during term time. Before the interview, I needed to make a translation to prove my English speaking abilities.

Skills test - mathematical (statistic, distribution) tasks and 2 cases. Interview with HR: 1) Guide me through you resume. 2) Why did you choose Nielsen? 3) What are your weaknesses and strengths? 4) What motivates you? Presentation - give recommendations to company, which launch a new product; interpret the graphs and surveys. No one informed about the final result.
