The interview process consists of 2 interviews, one with the tech leads of the development teams and one with the person in charge of the company at that location. The tech interview consists of a short intro talk where the company presents itself to you and you present yourself to the company. Then you proceed to a short list of technical questions, the answers to these are obvious and there are no tricks. None of the questions required prior knowledge of Unity or any 3D rendering software, they were all related to C# and the .NET platform.
