I had 3 skype interviews, 2 with the dev team I would be managing, which were a mixture of technical, organisation and process questions and one with the CTO. I was then asked to Berlin for 4 onsite interviews with the COO, CEO, Product Owner and HR. The whole process was organised very quickly, clearly and professionally which is a refreshing. I was fully compensated for my expenses. Even though I felt positive about the entire experience I was unfortunately not made an offer. The only criticism I have of the process is that I was not given any feedback, just a quick email from the recruiter.
