I applied through other source. The process took 12 months. I interviewed at Ipsos (Buenos Aires) in Dec 2015
Interview
Extremely long, yet very detailed and complete. Met will all of the countries and regional senior management, all the way up to the CEO of the region twice. It took too long because of re-organization internally, in normal condition's I would expect it to be shorter, but still, very long compared to other multinationals I interviewed with during my career.
