I worked at GfK full-time (More than 3 years)
Great people, global footprint with many fortune 500 clients, and also great reputation in many markets, pay was competitive
None I can think of, I would recommend GfK as an employer
I applied online. The process took 3 weeks. I interviewed at GfK.
The process started with a telephone interview with an HR recruiter. Fairly standard questions. Then I was invited to come into an office for an in-person interview. It turned out to be a group interview with several people, and they asked me to prepare a short presentation, guided by a specific outline.
