The interview took about 5 hours, with 5 different people. At the beginning there was a small presentation of the company and then we got the the actual talk. Everybody asked his own questions, starting from very technical details to career history, etc. Overall everybody was very nice, highly skilled and knowledgeable. Very good behaviour, very nice feedback. All the people I saw had a copy of my CV in front of them and were constantly taking notes on it. All underlined that the company has high demands from its employees, but the rewards are high.
