Had a short call after which I got an art test. They asked me to build, UV and texture a full vehicle. They wanted me to send them all the files associated with the model (Fbx, textures, high poly, etc). Something about the communication felt a bit off to me. It felt like they were going to use the model in their production process without hiring me. I could be wrong, but this was how I felt. I didn't end up submitting anything.
