I was approached on Linkedin for an interview, had a solide first interview and was asked to complete a home assignment within 7 days. Before my aloted 7 days we're up I recieved a cold automated email that the positon was filled. I continued to submit my home assignment which was entire project and full scope of work. I emailed and submitted directly to the person I had interviewed with, and inquired about the automated email I had recieved hours earlier. I never heard back, never recieved a response. If you're going to ask people to do a prospective job for you without pay, at least email them back personally.
