I applied through this position on Angel.co. I got a mail with a Python assignment to be submitted in a few days. After completing the assignment sent the code link back to them. But they never got back after the assignment. At least, I could have received the feedback regarding the assignment. I waited again for a few more days. When I searched for the job again in Angel.co the job was removed. I think this is probably their way of taking the work for free.
