Brand Embassy Software Developer interview questions

Beware this company.. Here is the story. They sent me a Game of Life task. I've implemented using best practices. However, beware this company. Because the contract they offered is legally problematic and they do not write salary on the contract. When I asked how they promise legally to pay the amount they offered, they said that I ask too many questions and withdrawn the offer.

The process consists of two interviews. During the first meeting we discuss my & company profile with COO Damián Brhel and second one was practical test of my programming skills.
