I was called three days before interview and they sheduled my interview. I naturally went for the interview and they gave me a product of their own to make a 3d model of it as a test. I modeled it very nicely and I was satisfied with the model I made. I made a very realistic and accurate 3d model of that product that they put in front of me. Then they checked it and they liked it too. They said they would let me know about the interview within a week. But they didn't communicate after that. They stopped replying to my calls and messages after a week.
