There was a research presentation for scientists and then two individual discussions with the managers at different levels. The questions were mostly about the personality and your preferred working style.
I applied through university. The process took 4 weeks. I interviewed at BASF (Ludwigshafen am Rhein) in Aug 2020
Interview
Very streamlined proces due to being in contact eith experts from the field rather than human resources. All the discussions were short pleasant and on point. In general was a very pleasant experience.
