I was invited for a telephone call as the first interview, checking my background and talking about my motivation. After the call I was invited to an on-site interview. The on-site interview took about 4 hours and included different exams about math, control theory and programming. After that I had interviews with different managers and with the HR department in the US. After that I met the team and had a short chat with them. All in all a very demanding interview, but ok with a little preparation.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
