Nielsen Intern, Professional Services Analytics Program interview questions

I applied online through my university's career site, where I submitted my resume and cover letter. After approximately three weeks, I was offered an interview. The process consisted of a 90-minute quantitative assessment and (approximately) a 30-minute interview. The 1-to-1 interview was primarily behavioral, but consisted of a few basic case questions, such as "a firm's sales are flat, but its market share is increasing. Explain this phenomenon."
