I applied through college or university. The process took 4 weeks. I interviewed at Kantar (Stamford, CT) in Nov 2010
Interview
First round consisted of a 1:1 interview that was resume based with one brain teaser/math problem. After that, final round at their offices in Wilton, CT. Math test (best to brush up using a GMAT math book) with 6 resume based interviews and lunch.
I applied through a recruiter. I interviewed at Kantar (Abidjan) in May 2019
Interview
The recruiter reached out to me on Facebook and requested me to send across my CV if I was interested. I then had an online interview with her. Later on, I had other rounds of interviews with local managers and underwent a test. I was successful in the end.
