I did this interview long ago (12+ months). The interview consisted in an assignment (make a game prototype). I did the game they supposed they want in a weekend and sent it by email. To me it was even more that they asked (even my friends like to play it a lot). The evaluation process took long, more than a month to receive a response. In the end they said "It's not what they expected", but gave no other feedback. I wonder what they did actually expect to improve it for future works, since I thought I did even more than required. This is the only negative aspect I found of this interview process.
