I applied online. The process took 4 days. I interviewed at Avantor (Fontenay-sous-Bois) in Sep 2019
Interview
At the time of my interview I was with the director of the service and one of the persons in charge of the service. They asked me some questions about the company that I was able to answer and asked me if I knew the software used and then some questions about situations to understand how I could be useful in the situations they might encounter.
Then I had an interview with the HR department to confirm what they said and to see if everything was coherent.
