Firstly, there was a phone call where they would interview you for around 15-20 minutes briefly. If you answer confidently and correctly, you will proceed to the next virtual interview with more technical questions and personal info. This is where you would have to be more confident and show how excited you are to join. The last interview are face to face with 3 interviewers with high roles in your department and most of the questions are technical. For my experience it was very positive and the conversation we had made me feel inspired to become successful like them.
