The interview process took about two months. Scientific interviews with the perspective leader and team mates were very interesting and challenging. Questions were difficult, but it was really amazing to think together to find answers, and I learnt a lot during the process. The interview with "big bosses", heads of sections I'd never see during work, went bad: my organic chemistry was a bit rusty (I applied for a computational position). They were aiming at making me uncomfortable with their behaviour and questions: I had the feeling I really didn't want to work with these people, so in the end I'm glad I didn't receive an offer.

Recruiter screen, then manager interview. Manager was looking for specific skills. There was a list of skills that were not listed in the job posting but were important for the position.
