Extensive logical/math tests and two interviews. First one with HR and direct superior, second one also with COO. During the process they were like: "we like you, you have a very high chance to get an offer". Feedback was like 30 seconds call: "we don't want you because you asked for too much money"

Initial Interview, Tests, Interview with Hiring Manager, Interview with Management and with President. Hiring manager was very kind and open to anwser all the questions. HR was also very kind.
