At first they will ask you questions in broken english and when you don't understand and ask for clarification they make it seem like it's your fault. Then later you do make a Unity prototype in 2 hours. In my case they told me they would call me after the 2 hours and didn't, then a few hours later they told me that I worked on it too long, and then proceeded to ignore me. Very unprofessional and a big waste of time.
