Application
I applied through an employee referral. The process took 2 weeks. I interviewed at Kantar in Jan 2014
Interview
Phone interview, series of tests then skype interview. Tests were difficult and you should plan on being alone in a quiet space where you can concentrate while you take them. The interview mostly concentrated on language and computer skills. It would be helpful to brush up on Microsoft Office skills before applying.
Interview questions [1]
Question 1
What do you think is the average day of a research executive? What is your educational background?
First there are 3 online exams: logic, verbal, and math. take your time - they are not difficult but have many traps.
After if you pass the exams you will have an interview with the Director, Business Director and HR.
1hr of a "case study" analyzing slides and looking for numbers or data that do not make sense - essentially looking for errors.
