Double Helix Games interview questions

I have applied this company at online. then Someone in HR called me one week later. We made an appointment phone interview next day. Supervisor asked me about how to create normal map, HOw much know about this company., and so on... actually I didn't know this company, so interview was pretty normal, and result is bad. They told me you will get a test soon, but they never called me back again. That's it.
