The application was for a position on their subsidiary startup trinamix GmbH. The whole interview process was well-organized and professionally handled. The only drawback was that there were too many interviews, 4 sets of interviews at different dates. It started with a phone interview with the hr recruiter. Then another phone interview with a technical person. Then an interview day where 12 people interview you two at a time and on top of that you have to give a presentation of past research work plus a research proposal on the job position you are applying for. So that entailed that I had to go over hundreds of pages of their patents. Then another interview day with 4 more people.
