Interview was nice and smooth, with no hr, with management from start. They gave me test task, which need a lot of years of experience in 3d, and game industry, and AR, which I basically have, but they agreed salary less then probably cleaner in their office have. I just told them the salary I used to have in my home country where living is half the price of Berlin and it turned out to be too much for them. So I refused to do such test.
