I applied online. The process took 2 months. I interviewed at Ecolab (Zúrich) in Feb 2018
Interview
Classic process with online tests, video interview and assessment centre.
The video interview wasn't any different from usual, with 5-6 questions and around 2 minutes per question to answer.
The assessment centre was made of 2 group exercises, an individual presentation which you have to prepare before the day and a 1 to 1 interview with someone from HR.
