I applied online. The process took 6 weeks. I interviewed at Colgate-Palmolive (Athens, Athens, Attica) in Sep 2016
Interview
In my first interview I was interviewed by the hr manager. In the process of case study I was interviewed by both the hr manager and the technical director. The same with the case study took place in my final interview. Both of them were really friendly. The questions were based on my cv and basically on my studies and prof. experience. The duration was about 30 minutes for the interview and almost 2 hours for the case study.
I applied through university. The process took 2 months. I interviewed at Colgate-Palmolive in Feb 2017
Interview
Very detailed oriented with 3 rounds, mostly focused on engineering fundamentals to the behavior-based questions. There was a written test before selection for interview. They will inform very soon about the selection for next round after each interview.
