After the first stage of the interview, is he/she liked it, you needed to present your career and resume for their group. I did and afterthat I rejected. There are some times a two-stage interview process in Germany. The econd stage is a little bit difficult than the first one.
I'm going for the PhD interview at max planck. may be silly but could you suggest, whether formal dressing (blazers/formal pants etc) are required to be worn or tees-jeans-informal jacket will be alright?
