I applied online. The process took 3 months. I interviewed at CERN (Genf) in Nov 2018
Interview
50 minutes talk at the whiteboard to present the main results and steps of the past career. The panel can interrupt the candidate at any time and is up to the candidate to manage to present all the relevant work regardless the interruption in the given time. In the last 10minutes the candidate is asked to present the project he would work on if selected.
