Found the job on LinkedIn and applied directly to Kantar. Had a telephone interview after about 2-3 weeks and then a formal interview a few weeks later. Interviewers really friendly throughout the whole process. 2nd stage interview split into 2 parts. Part 1: 3 tasks: 1. Logic task - working out what statement goes next in a sequence 2. Data interpretation task - looking at a table of figures and sharing any observations/criticisms 3. Excel task - % increase, v lookup, conditional Part 2: Verbal interview.
