I had 3 interviews: one with HR, one with the team Director, and one with 2 members of the team. Interviews lasted between 20 and 40 minutes, and included mostly motivation and skill-related questions. I wasn't asked about technical matters in deep. After completing the final interview, I was told I would receive a final answer from them, whether it was positive or negative. However, I never received any further communication, despite sending a follow-up email.
