Was good enough, not hard, I was asked about my education and experience. Atmosphere was nice, even friendly, we talked both in English and French, I showed all my knowledge
Standard three rounds of interviews with hr / manager / department head, mostly interested in past experience and case solving + usual questions about expectations and goals, nothing particularly hard
All was good. The usual questions as in most interviews. The interviewer is very nice. The security service takes a very long time to check. The offer is given quickly, but it takes a very long time to complete.
