Applied through a friend. Was asked about programming experience in OpenGL and artificial intelligence. Was given a phone interview several days later, discussed resume and graphics settings; what I use in games I play, and what I'd use in an ideal setup. In person interview consisted of more personality questions, a graphics themed 'spot the differences' quiz, an example of how to submit a bug report, and finally a couple sessions of Heroes of the Storm. HR seemed disorganized, occasionally only sending me new information after a reminder email, even getting the time of my in person interview wrong due to timezone differences.
