I was contacted on LinkedIn. After an hour of the interview process, I was told I have to make a test work. Had to make a 3D presentation of some random scientific topic they gave me. I had about 1-2 days to finish it. The whole thing was a mess, had to ask a bunch of questions that they never even answered. After I completed my task and sent it, they just ghosted me, never contacted me again, not a word. They just scammed me to do work for them.
