They asked for a game prototype to be made. After that face to face interview at their office.
Looks like they value memory power than problem solving, design, practical coding skills or analytical ability.
This was kind of disappointing. I was ready for a live coding test as well to prove my skills. Also I wasn't given any feedback on what went right and what went wrong etc. It would have been nice as I had to spend my time to make the game prototype and travel to the location to attend etc.
