I applied online. The process took 2 weeks. I interviewed at Tetra Pak (Lausanne, Vaud) in Sep 2015
Interview
Interview process was in three parts, including a case study, presentation and the actual interview. I was given 30 minutes to read a case study and prepare a presentation to the interview panelists. Presentation was on a flip board. After the presentation there was the usual question and answer session before the real interview began. The interview itself was standard and lasted for about an hour.
