The interview process was a three stage process, phone interview, "technical challenge" and final interview. The so-called "technical challenge" ended up being an improvised "technical challenge" with a Github repository. It was in a video call, with two developers, where we just build a 2D maze game with no direction or goal specified during this "technical challenge". After completing that interview stage, I was thanked for "being a guinea pig" for this experimental interview they've just conducted, during the video call by the developer leading the video call interview.
