I had phone interview, then I was given a interview project. I was asked about what I know about the company. Since I did some research, I answered that question. However, then I was asked what's difference between two finance terms. (I applied for a software engineer job, just saying.) Glad I have some finance majored friends, so I answered that questions. Then I was given a project to complete. It took me about five days to complete this project, and I did great follow up as well as communication with them. However, I got rejected with no feedback about the project I did. It was a at least one day project for people who has worked on the same topic before. I think it's a polite/reasonable thing to do to provide with some feedback to candidate who spent their time on the project. I followed up the email with my request for feedback, then I realized the email was sent by a no-reply email. At that point, it was more an insult than just a rejection email.
