Very long job interview. It lasted 3 hours, spoke with 2 different "technical" teams with different expertise plus last hour was dedicated to the classical human resources questions. However, positive experience, they were always kind and I felt comfortable.

I applied online. I only made it to the first interview, which was technical. I think usually there is one first interview (around 1 hour) and then the final interview is half a day of interviews (3 interviews: one technical, one values, and one meeting the hiring director).
