Joined a video call with an audio programmer and head of programming who were both friendly. was asked non technical like and technical questions about geometry, matrixes C++ template libraries and inheritance.

The companies first response was by email to allocate a time for an informal call via video chat. There, I was given the general rundown of the next interview stages. These were a chat with the lead engineer, a supervised coding test and a final interview. I was told that the final interview is rather a "get to know another" form of interview and that one has the role if one gets to that stage. After the initial stage, the interviewer has to sign an NDA.
