Good, respectful, hard at technical part. HR contacted me by email and then skype. Always very respectful and informative. Had to exchange some emails and then scheduled a technical test. Person to test got late but OK. Had 1 more intervel in the same week. had to wait 1 week for another interview about myself, personal information and background. Another technical interview happened I do not remember when. Took some weeks and a new quick call and then CEO interview that was nice and quick. Everything was OK except that take a little long but it is expected in this industry.
