The process began with a virtual interview with a recruiter. This was mostly me introducing myself, and I feel this was mostly a filter for the less serious applicants. Then I had a virtual interview with my to-be boss and a couple others including a colleague from the team. This was a chat and less technical focused and more about me as a person. Finally, the in-person interview in Billund. I was given a "case" to prepare before the interview. Then we discussed this case with the hiring manager, a lead engineer and another senior engineer. This was also very good, but perhaps it wasn't too clear how long one should spend preparing the case.
