A first interview with HR/basic HR questions. A second interview with a VP. A third one with hiring manager. Then, a business case to prepare at home and a 1 hour presentation in their office in front of these two persons, which ran smoothly. Of course, presentation has to be made in english. I never received a reply despite what I was told in the office and reminder email sent to HR who replied "I come back to you soon". Having candidates "work" during a hiring process is highly questionable and not acceptable especially when the company is not able to send simple emails, call candidates after having set up such a foolish and twisted process. Do not engage in a hiring process with them. You will loose your time and will not be respected.
