DNV Geotechnical Engineer interview questions

Got an interview as soon as the application period closed. The process seemed to be fast but then I had 3 months of waiting without any kind of answer, and did not get a feedback about it since then. Before the interview, I was asked some questions by e-mail and then the interview was with an HR and the head of the department. Both of them were very nice, mostly the HR, it is a pity they let you hang for so long without any feedback or response.
